    + *
  1. Every event is a standalone JSON clause
    2. + *
  2. Time is published as a time_t event since 1/1/1970 + * -this is the fastest to generate.
    3. + *
  3. An ISO date is generated, but this is cached and will only be accurate to within a second
    4. + *
  4. the stack trace is included as an array
    5. + *
+ * + * A simple log event will resemble the following + * 
+ *     {"name":"test","time":1318429136789,"date":"2011-10-12 15:18:56,789","level":"INFO","thread":"main","message":"test message"}

+/**
+ * This is intended to test the LinuxContainerExecutor code, but because of
+ * some security restrictions this can only be done with some special setup
+ * first.
+ * 
    
+ * 
  1. Compile the code with container-executor.conf.dir set to the location you
+ * want for testing.
+ * 
    
+ * > mvn clean install -Pnative -Dcontainer-executor.conf.dir=/etc/hadoop
+ *                          -DskipTests
+ * 
    
+ * 
+ * 
  2. Set up ${container-executor.conf.dir}/container-executor.cfg
+ * container-executor.cfg needs to be owned by root and have in it the proper
+ * config values.
+ * 
    
+ * > cat /etc/hadoop/container-executor.cfg
+ * yarn.nodemanager.local-dirs=/tmp/hadoop/nm-local/
+ * yarn.nodemanager.log-dirs=/tmp/hadoop/nm-log
+ * yarn.nodemanager.linux-container-executor.group=mapred
+ * #depending on the user id of the application.submitter option
+ * min.user.id=1
+ * > sudo chown root:root /etc/hadoop/container-executor.cfg
+ * > sudo chmod 444 /etc/hadoop/container-executor.cfg
+ * 
    
+ * 
+ * 
  3. iMove the binary and set proper permissions on it. It needs to be owned 
+ * by root, the group needs to be the group configured in container-executor.cfg, 
+ * and it needs the setuid bit set. (The build will also overwrite it so you
+ * need to move it to a place that you can support it. 
+ * 
    
+ * > cp ./hadoop-mapreduce-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-nodemanager/src/main/c/container-executor/container-executor /tmp/
+ * > sudo chown root:mapred /tmp/container-executor
+ * > sudo chmod 4550 /tmp/container-executor
+ * 
    
+ * 
+ * 
  4. Run the tests with the execution enabled (The user you run the tests as
+ * needs to be part of the group from the config.
+ * 
    
+ * mvn test -Dtest=TestLinuxContainerExecutor -Dapplication.submitter=nobody -Dcontainer-executor.path=/tmp/container-executor
+ * 
    
+ *

+Hadoop MapReduce Next Generation - Cluster Setup
+
+  \[ {{{./index.html}Go Back}} \]
+
+%{toc|section=1|fromDepth=0}
+
+* {Purpose}
+
+  This document describes how to install, configure and manage non-trivial 
+  Hadoop clusters ranging from a few nodes to extremely large clusters 
+  with thousands of nodes.
+
+  To play with Hadoop, you may first want to install it on a single 
+  machine (see {{{SingleCluster}Single Node Setup}}).
+  
+* {Prerequisites}
+
+  Download a stable version of Hadoop from Apache mirrors.
+  
+* {Installation}
+
+  Installing a Hadoop cluster typically involves unpacking the software on all 
+  the machines in the cluster or installing RPMs.
+
+  Typically one machine in the cluster is designated as the NameNode and 
+  another machine the as ResourceManager, exclusively. These are the masters. 
+  
+  The rest of the machines in the cluster act as both DataNode and NodeManager. 
+  These are the slaves.
+
+* {Running Hadoop in Non-Secure Mode}
+
+  The following sections describe how to configure a Hadoop cluster.
+
+  * {Configuration Files}
+  
+    Hadoop configuration is driven by two types of important configuration files:
+
+      * Read-only default configuration - <<>>, 
+        <<>>, <<>> and 
+        <<>>.
+        
+      * Site-specific configuration - <>, 
+        <>, <> and 
+        <>.
+
+
+    Additionally, you can control the Hadoop scripts found in the bin/ 
+    directory of the distribution, by setting site-specific values via the 
+    <> and <>.
+
+  * {Site Configuration}
+  
+  To configure the Hadoop cluster you will need to configure the 
+  <<>> in which the Hadoop daemons execute as well as the 
+  <<>> for the Hadoop daemons.
+
+  The Hadoop daemons are NameNode/DataNode and ResourceManager/NodeManager.
+
+
+    * {Configuring Environment of Hadoop Daemons}
+    
+    Administrators should use the <> and 
+    <> script to do site-specific customization of the 
+    Hadoop daemons' process environment.
+
+    At the very least you should specify the <<>> so that it is 
+    correctly defined on each remote node.
+
+    Administrators can configure individual daemons using the configuration 
+    options shown below in the table:
+
+*--------------------------------------+--------------------------------------+
+|| Daemon                              || Environment Variable                |
+*--------------------------------------+--------------------------------------+
+| NameNode                             | HADOOP_NAMENODE_OPTS                 |
+*--------------------------------------+--------------------------------------+
+| DataNode                             | HADOOP_DATANODE_OPTS                 |
+*--------------------------------------+--------------------------------------+
+| Backup NameNode                      | HADOOP_SECONDARYNAMENODE_OPTS        |
+*--------------------------------------+--------------------------------------+
+| ResourceManager                      | YARN_RESOURCEMANAGER_OPTS            |
+*--------------------------------------+--------------------------------------+
+| NodeManager                          | YARN_NODEMANAGER_OPTS                |
+*--------------------------------------+--------------------------------------+
+| WebAppProxy                          | YARN_PROXYSERVER_OPTS                |
+*--------------------------------------+--------------------------------------+
+
+    For example, To configure Namenode to use parallelGC, the following 
+    statement should be added in hadoop-env.sh :
+     
+----
+    export HADOOP_NAMENODE_OPTS="-XX:+UseParallelGC ${HADOOP_NAMENODE_OPTS}" 
+----
+    
+    Other useful configuration parameters that you can customize include:
+
+      * <<>> / <<>> - The directory where the 
+        daemons' log files are stored. They are automatically created if they 
+        don't exist.
+        
+      * <<>> / <<>> - The maximum amount of 
+        heapsize to use, in MB e.g. 1000MB. This is used to configure the heap 
+        size for the daemon. By default, the value is 1000MB.
+
+  
+    * {Configuring the Hadoop Daemons in Non-Secure Mode}
+
+      This section deals with important parameters to be specified in 
+      the given configuration files:
+

+*-------------------------+-------------------------+------------------------+
+
+      * Hadoop Rack Awareness
+      
+      The HDFS and the YARN components are rack-aware.
+
+      The NameNode and the ResourceManager obtains the rack information of the 
+      slaves in the cluster by invoking an API  in an administrator 
+      configured module. 
+      
+      The API resolves the DNS name (also IP address) to a rack id. 
+      
+      The site-specific module to use can be configured using the configuration 
+      item <<>>. The default implementation 
+      of the same runs a script/command configured using 
+      <<>>. If <<>> is 
+      not set, the rack id  is returned for any passed IP address. 
+
+      * Monitoring Health of NodeManagers
+      
+      Hadoop provides a mechanism by which administrators can configure the 
+      NodeManager to run an administrator supplied script periodically to 
+      determine if a node is healthy or not. 
+      
+      Administrators can determine if the node is in a healthy state by 
+      performing any checks of their choice in the script. If the script 
+      detects the node to be in an unhealthy state, it must print a line to 
+      standard output beginning with the string ERROR. The NodeManager spawns 
+      the script periodically and checks its output. If the script's output 
+      contains the string ERROR, as described above, the node's status is 
+      reported as <<>> and the node is black-listed by the 
+      ResourceManager. No further tasks will be assigned to this node. 
+      However, the NodeManager continues to run the script, so that if the 
+      node becomes healthy again, it will be removed from the blacklisted nodes
+      on the ResourceManager automatically. The node's health along with the 
+      output of the script, if it is unhealthy, is available to the 
+      administrator in the ResourceManager web interface. The time since the 
+      node was healthy is also displayed on the web interface.
+
+      The following parameters can be used to control the node health 
+      monitoring script in <<>>.
+
+*-------------------------+-------------------------+------------------------+
+|| Parameter              || Value                  || Notes                 |
+*-------------------------+-------------------------+------------------------+
+| <<>> | | |
+| | Node health script  | |
+| | | Script to check for node's health status. |
+*-------------------------+-------------------------+------------------------+
+| <<>> | | |
+| | Node health script options  | |
+| | | Options for script to check for node's health status. |
+*-------------------------+-------------------------+------------------------+

+| | Node health script interval  | |
+| | | Time interval for running health script. |
+*-------------------------+-------------------------+------------------------+
+| <<>> | | |
+| | Node health script timeout interval  | |
+| | | Timeout for health script execution. |
+*-------------------------+-------------------------+------------------------+
+
+    * {Slaves file}
+      
+    Typically you choose one machine in the cluster to act as the NameNode and 
+    one machine as to act as the ResourceManager, exclusively. The rest of the 
+    machines act as both a DataNode and NodeManager and are referred to as 
+    .
+
+    List all slave hostnames or IP addresses in your <<>> file, 
+    one per line.
+
+    * {Logging}
+    
+    Hadoop uses the Apache log4j via the Apache Commons Logging framework for 
+    logging. Edit the <<>> file to customize the 
+    Hadoop daemons' logging configuration (log-formats and so on).
+    
+  * {Operating the Hadoop Cluster}
+
+  Once all the necessary configuration is complete, distribute the files to the 
+  <<>> directory on all the machines.
+
+    * Hadoop Startup
+  
+    To start a Hadoop cluster you will need to start both the HDFS and YARN 
+    cluster.
+
+    Format a new distributed filesystem:
+  
+----
+  $ $HADOOP_PREFIX_HOME/bin/hdfs namenode -format 
+----
+
+    Start the HDFS with the following command, run on the designated NameNode:
+  
+----
+  $ $HADOOP_PREFIX_HOME/bin/hdfs start namenode --config $HADOOP_CONF_DIR  
+----    	  
+
+    Run a script to start DataNodes on all slaves:
+
+----
+  $ $HADOOP_PREFIX_HOME/bin/hdfs start datanode --config $HADOOP_CONF_DIR  
+----    	  
+  
+    Start the YARN with the following command, run on the designated 
+    ResourceManager:
+  
+----
+  $ $YARN_HOME/bin/yarn start resourcemanager --config $HADOOP_CONF_DIR  
+----    	  
+
+    Run a script to start NodeManagers on all slaves:
+
+----
+  $ $YARN_HOME/bin/yarn start nodemanager --config $HADOOP_CONF_DIR  
+----    	  
+
+    Start a standalone WebAppProxy server.  If multiple servers
+    are used with load balancing it should be run on each of them:
+
+----
+  $ $YARN_HOME/bin/yarn start proxyserver --config $HADOOP_CONF_DIR  
+----
+
+    Start the MapReduce JobHistory Server with the following command, run on the  
+    designated server:
+  
+----
+  $ $YARN_HOME/bin/yarn start historyserver --config $HADOOP_CONF_DIR  
+----    	  
+
+    * Hadoop Shutdown      
+
+    Stop the NameNode with the following command, run on the designated 
+    NameNode:
+  
+----
+  $ $HADOOP_PREFIX_HOME/bin/hdfs stop namenode --config $HADOOP_CONF_DIR  
+----    	  
+
+    Run a script to stop DataNodes on all slaves:
+
+----
+  $ $HADOOP_PREFIX_HOME/bin/hdfs stop datanode --config $HADOOP_CONF_DIR  
+----    	  
+  
+    Stop the ResourceManager with the following command, run on the designated 
+    ResourceManager:
+  
+----
+  $ $YARN_HOME/bin/yarn stop resourcemanager --config $HADOOP_CONF_DIR  
+----    	  
+
+    Run a script to stop NodeManagers on all slaves:
+
+----
+  $ $YARN_HOME/bin/yarn stop nodemanager --config $HADOOP_CONF_DIR  
+----    	  
+
+    Stop the WebAppProxy server. If multiple servers are used with load
+    balancing it should be run on each of them:
+
+----
+  $ $YARN_HOME/bin/yarn stop proxyserver --config $HADOOP_CONF_DIR  
+----
+
+
+    Stop the MapReduce JobHistory Server with the following command, run on the  
+    designated server:
+  
+----
+  $ $YARN_HOME/bin/yarn stop historyserver --config $HADOOP_CONF_DIR  
+----

+      A <<>> used by YARN framework which define how any

+      The following are the available in Hadoop YARN:
+
+*--------------------------------------+--------------------------------------+
+|| ContainerExecutor                   || Description                         |
+*--------------------------------------+--------------------------------------+
+| <<>>             | |
+| | The default executor which YARN uses to manage container execution. |
+| | The container process has the same Unix user as the NodeManager.  |
+*--------------------------------------+--------------------------------------+
+| <<>>               | |
+| | Supported only on GNU/Linux, this executor runs the containers as the | 
+| | user who submitted the application. It requires all user accounts to be |
+| | created on the cluster nodes where the containers are launched. It uses |
+| | a  executable that is included in the Hadoop distribution. |
+| | The NodeManager uses this executable to launch and kill containers. |
+| | The setuid executable switches to the user who has submitted the |
+| | application and launches or kills the containers. For maximum security, |
+| | this executor sets up restricted permissions and user/group ownership of |
+| | local files and directories used by the containers such as the shared |
+| | objects, jars, intermediate files, log files etc. Particularly note that, |
+| | because of this, except the application owner and NodeManager, no other |
+| | user can access any of the local files/directories including those |
+| | localized as part of the distributed cache. |
+*--------------------------------------+--------------------------------------+
+
+      To build the LinuxContainerExecutor executable run:
+        
+----
+ $ mvn package -Dcontainer-executor.conf.dir=/etc/hadoop/
+----
+        
+      The path passed in <<<-Dcontainer-executor.conf.dir>>> should be the 
+      path on the cluster nodes where a configuration file for the setuid 
+      executable should be located. The executable should be installed in
+      $YARN_HOME/bin.
+
+      The executable must have specific permissions: 6050 or --Sr-s--- 
+      permissions user-owned by  (super-user) and group-owned by a 
+      special group (e.g. <<>>) of which the NodeManager Unix user is 
+      the group member and no ordinary application user is. If any application 
+      user belongs to this special group, security will be compromised. This 
+      special group name should be specified for the configuration property 
+      <<>> in both 
+      <<>> and <<>>. 
+      
+      For example, let's say that the NodeManager is run as user  who is 
+      part of the groups users and , any of them being the primary group.
+      Let also be that  has both  and another user 
+      (application submitter)  as its members, and  does not 
+      belong to . Going by the above description, the setuid/setgid 
+      executable should be set 6050 or --Sr-s--- with user-owner as  and 
+      group-owner as  which has  as its member (and not  
+      which has  also as its member besides ).
+
+      The LinuxTaskController requires that paths including and leading up to 
+      the directories specified in <<>> and 
+      <<>> to be set 755 permissions as described 
+      above in the table on permissions on directories.
+
+        * <<>>
+        
+        The executable requires a configuration file called 
+        <<>> to be present in the configuration 
+        directory passed to the mvn target mentioned above. 
+
+        The configuration file must be owned by the user running NodeManager 
+        (user <<>> in the above example), group-owned by anyone and 
+        should have the permissions 0400 or r--------.
+
+        The executable requires following configuration items to be present 
+        in the <<>> file. The items should be 
+        mentioned as simple key=value pairs, one per-line:

+HDFS Federation
+
+  \[ {{{./index.html}Go Back}} \]
+
+%{toc|section=1|fromDepth=0}
+
+  This guide provides an overview of the HDFS Federation feature and
+  how to configure and manage the federated cluster.
+
+* {Background}
+
+[./federation-background.gif] HDFS Layers
+
+  HDFS has two main layers:
+
+  * <>
+
+    * Consists of directories, files and blocks
+
+    * It supports all the namespace related file system operations such as 
+      create, delete, modify and list files and directories.
+
+  * <> has two parts
+
+    * Block Management (which is done in Namenode)
+
+      * Provides datanode cluster membership by handling registrations, and 
+        periodic heart beats.
+
+      * Processes block reports and maintains location of blocks.
+
+      * Supports block related operations such as create, delete, modify and 
+        get block location.
+
+      * Manages replica placement and replication of a block for under 
+        replicated blocks and deletes blocks that are over replicated.
+
+    * Storage - is provided by datanodes by storing blocks on the local file 
+      system and allows read/write access.
+
+  The current HDFS architecture allows only a single namespace for the 
+  entire cluster. A single Namenode manages this namespace. HDFS 
+  Federation addresses limitation of current architecture by adding 
+  support multiple Namenodes/namespaces to HDFS file system.
+    
+* {HDFS Federation}
+
+  In order to scale the name service horizontally, federation uses multiple 
+  independent Namenodes/namespaces. The Namenodes are federated, that is, the 
+  Namenodes are independent and don’t require coordination with each other. 
+  The datanodes are used as common storage for blocks by all the Namenodes. 
+  Each datanode registers with all the Namenodes in the cluster. Datanodes 
+  send periodic heartbeats and block reports and handles commands from the 
+  Namenodes.
+
+[./federation.gif] HDFS Federation Architecture
+
+
+  <>
+
+  A Block Pool is a set of blocks that belong to a single namespace. 
+  Datanodes store blocks for all the block pools in the cluster.
+  It is managed independently of other block pools. This allows a namespace 
+  to generate Block IDs for new blocks without the need for coordination 
+  with the other namespaces. The failure of a Namenode does not prevent 
+  the datanode from serving other Namenodes in the cluster.
+
+  A Namespace and its block pool together are called Namespace Volume. 
+  It is a self-contained unit of management. When a Namenode/namespace 
+  is deleted, the corresponding block pool at the datanodes is deleted.
+  Each namespace volume is upgraded as a unit, during cluster upgrade.
+
+  <>
+
+  A new identifier <> is added to identify all the nodes in 
+  the cluster.  When a Namenode is formatted, this identifier is provided 
+  or auto generated. This ID should be used for formatting the other 
+  Namenodes into the cluster.
+
+** Key Benefits
+
+  * Namespace Scalability - HDFS cluster storage scales horizontally but 
+    the namespace does not. Large deployments or deployments using lot 
+    of small files benefit from scaling the namespace by adding more 
+    Namenodes to the cluster
+
+  * Performance - File system operation throughput is currently limited 
+    by a single Namenode. Adding more Namenodes to the cluster scales the 
+    file system read/write operations throughput.
+
+  * Isolation - A single Namenode offers no isolation in multi user 
+    environment. An experimental application can overload the Namenode 
+    and slow down production critical applications. With multiple Namenodes, 
+    different categories of applications and users can be isolated to 
+    different namespaces.
+
+* {Federation Configuration}
+
+  Federation configuration is <> and allows existing 
+  single Namenode configuration to work without any change. The new 
+  configuration is designed such that all the nodes in the cluster have 
+  same configuration without the need for deploying different configuration 
+  based on the type of the node in the cluster.
+
+  A new abstraction called <<>> is added with
+  federation. The Namenode and its corresponding secondary/backup/checkpointer
+  nodes belong to this. To support single configuration file, the Namenode and
+  secondary/backup/checkpointer configuration parameters are suffixed with
+  <<>> and are added to the same configuration file.
+
+
+** Configuration:
+
+  <>: Add the following parameters to your configuration:
+  <<>>: Configure with list of comma separated 
+  NameServiceIDs. This will be used by Datanodes to determine all the 
+  Namenodes in the cluster.
+  
+  <>: For each Namenode and Secondary Namenode/BackupNode/Checkpointer 
+  add the following configuration suffixed with the corresponding 
+  <<>> into the common configuration file.
+

+|                     | <<>>   |
+*---------------------+--------------------------------------------+
+    
+  Here is an example configuration with two namenodes:
+
+----
+
+  
+    dfs.federation.nameservices
+    ns1,ns2
+  
+  
+    dfs.namenode.rpc-address.ns1
+    hdfs://nn-host1:rpc-port
+  
+  
+    dfs.namenode.http-address.ns1
+    nn-host1:http-port
+  
+  
+    dfs.namenode.secondaryhttp-address.ns1
+    snn-host1:http-port
+  
+  
+    dfs.namenode.rpc-address.ns2
+    hdfs://nn-host2:rpc-port
+  
+  
+    dfs.namenode.http-address.ns2
+    nn-host2:http-port
+  
+  
+    dfs.namenode.secondaryhttp-address.ns2
+    snn-host2:http-port
+  
+
+  .... Other common configuration ...
+
+----
+
+** Formatting Namenodes
+
+  <>: Format a namenode using the following command:
+  
+----
+> $HADOOP_PREFIX_HOME/bin/hdfs namenode -format [-clusterId ]
+----
+  Choose a unique cluster_id, which will not conflict other clusters in 
+  your environment. If it is not provided, then a unique ClusterID is 
+  auto generated.
+
+  <>: Format additional namenode using the following command:
+
+----
+> $HADOOP_PREFIX_HOME/bin/hdfs namenode -format -clusterId 
+----
+  Note that the cluster_id in step 2 must be same as that of the 
+  cluster_id in step 1. If they are different, the additional Namenodes 
+  will not be part of the federated cluster.
+
+** Upgrading from older release to 0.23 and configuring federation
+
+  Older releases supported a single Namenode. Here are the steps enable 
+  federation:
+
+  Step 1: Upgrade the cluster to newer release. During upgrade you can 
+  provide a ClusterID as follows:
+
+----
+> $HADOOP_PREFIX_HOME/bin/hdfs start namenode --config $HADOOP_CONF_DIR  -upgrade -clusterId 
+----
+  If ClusterID is not provided, it is auto generated.
+
+** Adding a new Namenode to an existing HDFS cluster
+
+  Follow the following steps:
+
+  * Add configuration parameter <<>> to 
+    the configuration.
+
+  * Update the configuration with NameServiceID suffix. Configuration 
+    key names have changed post release 0.20. You must use new configuration 
+    parameter names, for federation.
+
+  * Add new Namenode related config to the configuration files.
+
+  * Propagate the configuration file to the all the nodes in the cluster.
+
+  * Start the new Namenode, Secondary/Backup.
+
+  * Refresh the datanodes to pickup the newly added Namenode by running 
+    the following command:
+
+----
+> $HADOOP_PREFIX_HOME/bin/hdfs dfadmin -refreshNameNode :
+----
+
+  * The above command must be run against all the datanodes in the cluster.
+
+* {Managing the cluster}
+
+**  Starting and stopping cluster
+
+  To start the cluster run the following command:
+
+----
+> $HADOOP_PREFIX_HOME/bin/start-dfs.sh
+----
+
+  To start the cluster run the following command:
+
+----
+> $HADOOP_PREFIX_HOME/bin/stop-dfs.sh
+----
+
+  These commands can be run from any node where the HDFS configuration is 
+  available.  The command uses configuration to determine the Namenodes 
+  in the cluster and starts the Namenode process on those nodes. The 
+  datanodes are started on nodes specified in the <<>> file. The 
+  script can be used as reference for building your own scripts for 
+  starting and stopping the cluster.
+
+**  Balancer
+
+  Balancer has been changed to work with multiple Namenodes in the cluster to 
+  balance the cluster. Balancer can be run using the command:
+
+----
+"$HADOOP_PREFIX"/bin/hadoop-daemon.sh --config $HADOOP_CONF_DIR --script "$bin"/hdfs start balancer [-policy ]
+----
+
+  Policy could be:
+
+  * <<>> - this is the  policy. This balances the storage at 
+    the datanode level. This is similar to balancing policy from prior releases.
+
+  * <<>> - this balances the storage at the block pool level. 
+    Balancing at block pool level balances storage at the datanode level also.
+
+  Note that Balander only balances the data and does not balance the namespace.
+
+** Decommissioning
+
+  Decommissioning is similar to prior releases. The nodes that need to be 
+  decommissioning are added to the exclude file at all the Namenode. Each 
+  Namenode decommissions its Block Pool. When all the Namenodes finish 
+  decommissioning a datanode, the datanode is considered to be decommissioned.
+
+  <>: To distributed an exclude file to all the Namenodes, use the 
+  following command:
+
+----
+"$HADOOP_PREFIX"/bin/distributed-exclude.sh 
+----
+
+  <>: Refresh all the Namenodes to pick up the new exclude file.
+
+----
+"$HADOOP_PREFIX"/bin/refresh-namenodes.sh
+----
+ 
+  The above command uses HDFS configuration to determine the Namenodes 
+  configured in the cluster and refreshes all the Namenodes to pick up 
+  the new exclude file.
+
+** Cluster Web Console
+
+  Similar to Namenode status web page, a Cluster Web Console is added in 
+  federation to monitor the federated cluster at 
+  <</dfsclusterhealth.jsp>>>.
+  Any Namenode in the cluster can be used to access this web page.
+
+  The web page provides the following information:
+
+  * Cluster summary that shows number of files, number of blocks and 
+    total configured storage capacity, available and used storage information 
+    for the entire cluster.
+
+  * Provides list of Namenodes and summary that includes number of files,
+    blocks, missing blocks, number of live and dead data nodes for each 
+    Namenode. It also provides a link to conveniently access Namenode web UI.
+
+  * It also provides decommissioning status of datanodes.

+Apache Hadoop NextGen MapReduce (YARN)
+
+  MapReduce has undergone a complete overhaul in hadoop-0.23 and we now have, 
+  what we call, MapReduce 2.0 (MRv2) or YARN.
+
+  The fundamental idea of MRv2 is to split up the two major functionalities of 
+  the JobTracker, resource management and job scheduling/monitoring, into 
+  separate daemons. The idea is to have a global ResourceManager () and 
+  per-application ApplicationMaster ().  An application is either a single 
+  job in the classical sense of Map-Reduce jobs or a DAG of jobs. 
+
+  The ResourceManager and per-node slave, the NodeManager (), form the 
+  data-computation framework. The ResourceManager is the ultimate authority that 
+  arbitrates resources among all the applications in the system. 
+
+  The per-application ApplicationMaster is, in effect, a framework specific 
+  library and is tasked with negotiating resources from the ResourceManager and 
+  working with the NodeManager(s) to execute and monitor the tasks.
+
+[./yarn_architecture.gif] MapReduce NextGen Architecture
+
+  The ResourceManager has two main components: Scheduler and 
+  ApplicationsManager.
+
+  The Scheduler is responsible for allocating resources to the various running 
+  applications subject to familiar constraints of capacities, queues etc. The 
+  Scheduler is pure scheduler in the sense that it performs no monitoring or 
+  tracking of status for the application. Also, it offers no guarantees about 
+  restarting failed tasks either due to application failure or hardware 
+  failures. The Scheduler performs its scheduling function based the resource 
+  requirements of the applications; it does so based on the abstract notion of 
+  a resource  which incorporates elements such as memory, cpu, disk, 
+  network etc. In the first version, only <<>> is supported. 
+
+  The Scheduler has a pluggable policy plug-in, which is responsible for 
+  partitioning the cluster resources among the various queues, applications etc. 
+  The current Map-Reduce schedulers such as the CapacityScheduler and the 
+  FairScheduler would be some examples of the plug-in. 
+
+  The CapacityScheduler supports <<>> to allow for more 
+  predictable sharing of cluster resources
+
+  The ApplicationsManager is responsible for accepting job-submissions, 
+  negotiating the first container for executing the application specific 
+  ApplicationMaster and provides the service for restarting the
+  ApplicationMaster container on failure.
+
+  The NodeManager is the per-machine framework agent who is responsible for 
+  containers, monitoring their resource usage (cpu, memory, disk, network) and 
+  reporting the same to the ResourceManager/Scheduler.
+
+  The per-application ApplicationMaster has the responsibility of negotiating 
+  appropriate resource containers from the Scheduler, tracking their status and 
+  monitoring for progress.
+
+  MRV2 maintains <> with previous stable release 
+  (hadoop-0.20.205).  This means that all Map-Reduce jobs should still run 
+  unchanged on top of MRv2 with just a recompile.

- * provides the following features: 
- *  * support for queues, where a job is submitted to a queue. 
- *  * Queues are assigned a fraction of the capacity of the grid (their
- *  'capacity') in the sense that a certain capacity of resources 
- *  will be at their disposal. All jobs submitted to the queues of an Org 
- *  will have access to the capacity to the Org.
- *  * Free resources can be allocated to any queue beyond its 
- *  capacity.
- *  * Queues optionally support job priorities (disabled by default). 
- *  * Within a queue, jobs with higher priority will have access to the 
- *  queue's resources before jobs with lower priority. However, once a job 
- *  is running, it will not be preempted for a higher priority job.
- *  * In order to prevent one or more users from monopolizing its resources, 
- *  each queue enforces a limit on the percentage of resources allocated to a 
- *  user at any given time, if there is competition for them.

-/**
- * This class asynchronously initializes jobs submitted to the
- * Map/Reduce cluster running with the {@link CapacityTaskScheduler}.
- *
- * 

- * The class comprises of a main poller thread, and a set of worker
- * threads that together initialize the jobs. The poller thread periodically
- * looks at jobs submitted to the scheduler, and selects a set of them
- * to be initialized. It passes these to the worker threads for initializing.
- * Each worker thread is configured to look at jobs submitted to a fixed
- * set of queues. It initializes jobs in a round robin manner - selecting
- * the first job in order from each queue ready to be initialized.
- * 

- * 
- * 

- * An initialized job occupies memory resources on the Job Tracker. Hence,
- * the poller limits the number of jobs initialized at any given time to
- * a configured limit. The limit is specified per user per queue.
- * 

- * 
- * 

- * However, since a job needs to be initialized before the scheduler can
- * select tasks from it to run, it tries to keep a backlog of jobs 
- * initialized so the scheduler does not need to wait and let empty slots
- * go waste. The core logic of the poller is to pick up the right jobs,
- * which have a good potential to be run next by the scheduler. To do this,
- * it picks up jobs submitted across users and across queues to account
- * both for guaranteed capacities and user limits. It also always initializes
- * high priority jobs, whenever they need to be initialized, even if this
- * means going over the limit for initialized jobs.

-   * want to initialize too many jobs as each initialized job has a memory
-   * footprint, sometimes significant.
-   * 
-   * Number of jobs to be initialized is restricted by two values: - Maximum

-   * of initialized jobs per user. The product of these two gives us the

-   * Note that this is a rough number, meant for decreasing extra memory
-   * footprint. It's OK if we go over it once in a while, if we have to.
-   * 
-   * This can happen as follows. Suppose we have initialized 3 jobs for a
-   * user. Now, suppose the user submits a job who's priority is higher than
-   * that of the 3 jobs initialized. This job needs to be initialized, since it
-   * will run earlier than the 3 jobs. We'll now have 4 initialized jobs for the
-   * user. If memory becomes a problem, we should ideally un-initialize one of
-   * the 3 jobs, to keep the count of initialized jobs at 3, but that's
-   * something we don't do for now. This situation can also arise when a new
-   * user submits a high priority job, thus superceeding a user whose jobs have
-   * already been initialized. The latter user's initialized jobs are redundant,
-   * but we'll leave them initialized.

-This package implements dynamic priority scheduling for MapReduce jobs.
-
-Overview
---------
-The purpose of this scheduler is to allow users to increase and decrease
-their queue priorities continuosly to meet the requirements of their
-current workloads. The scheduler is aware of the current demand and makes
-it more expensive to boost the priority under peak usage times. Thus
-users who move their workload to low usage times are rewarded with
-discounts. Priorities can only be boosted within a limited quota.
-All users are given a quota or a budget which is deducted periodically
-in configurable accounting intervals. How much of the budget is 
-deducted is determined by a per-user spending rate, which may
-be modified at any time directly by the user. The cluster slots 
-share allocated to a particular user is computed as that users
-spending rate over the sum of all spending rates in the same accounting
-period.
-
-Configuration
--------------
-This scheduler comprises two components, an accounting or resource allocation part that 
-manages and bills for queue shares, and a scheduler that
-enforces the queue shares in the form of map and reduce slots of running jobs.
-
-Hadoop Configuration (e.g. hadoop-site.xml):
-mapreduce.jobtracker.taskscheduler      
-    This needs to be set to 
-    org.apache.hadoop.mapred.DynamicPriorityScheduler
-    to use the dynamic scheduler.
-Scheduler Configuration:
-mapred.dynamic-scheduler.scheduler   
-    The Java path of the MapReduce scheduler that should
-    enforce the allocated shares.
-    Has been tested with (which is the default):
-    org.apache.hadoop.mapred.PriorityScheduler
-mapred.priority-scheduler.acl-file
-    Full path of ACL with syntax:
-        
-    separated by line feeds
-mapred.dynamic-scheduler.budget-file  
-    The full OS path of the file from which the
-    budgets are read and stored. The syntax of this file is:
-      
-    separated by newlines where budget can be specified
-    as a Java float. The file should not be edited
-    directly, if the server is running, but through the 
-    servlet API to ensure proper synchronization.
-
-mapred.dynamic-scheduler.alloc-interval       
-    Allocation interval, when the scheduler rereads the
-    spending rates and recalculates the cluster shares.
-    Specified as seconds between allocations.
-    Default is 20 seconds.
-
-Servlet API
-----------
-The queue should be managed through the Servlet REST API
-if the jobtracker server is running.
-
-It is installed at
-[job tracker URL]/scheduler
-operations supported: 
-  price       i
-    get the current price of the cluster 
-    (aggregate spending rates of queues with running or pending jobs)
-  time        
-    get start time of server and current time in epoch units 
-  info=queue_to_query 
-    get info about queue (requires user or admin privilege>
-  infos 
-    get info about all queues (requires admin privilege)
-  addBudget=budget_to_add,queue=queue_to_change 
-    add budget to queue (requires admin privilege)
-  setSpending=spending_to_set,queue=queue_to_change 
-    set spending rate of queue (requires user or admin privilege)
-  addQueue=queue_to_add 
-    add new queue  (requires admin privilege)
-  removeQueue=queue_to_remove 
-    remove queue (requires admin privilege)
-
-Example:
-  http://myhost:50030/scheduler?setSpending=0.01&queue=myqueue
-  The Authorization header is used for signing
-
-The signature is created akin to the AWS Query Authentication scheme
-HMAC_SHA1("&user=×tamp=", key)
-For the servlet operations query path is everything that comes after /scheduler?
-in the url. For job submission the query path is just the empty string "".
-Job submissions also need to set the following job properties:
--Dmapred.job.timestamp= 
--Dmapred.job.signature= -Dmapreduce.job.queue.name=
-Note queue must match the user submitting the job.
-
-Example python query 
---------------------------------
-import base64
-import hmac
-import sha
-import httplib, urllib
-import sys
-import time
-from popen2 import popen3
-import os
-
-def hmac_sha1(data, key):
-    return urllib.quote(base64.encodestring(hmac.new(key, data, sha).digest()).strip())
-
-stdout, stdin, stderr = popen3("id -un")
-USER = stdout.read().strip()
-f = open(os.path.expanduser("~/.ssh/hadoop_key"))
-KEY = f.read().strip()
-f.close()
-f = open(os.path.expanduser("/etc/hadoop_server"))
-SERVER = f.read().strip()
-f.close()
-URL = "/scheduler"
-conn = httplib.HTTPConnection(SERVER)
-params = sys.argv[1]
-params = params + "&user=%s×tamp=%d" % (USER,long(time.time()*1000))
-print params
-headers = {"Authorization": hmac_sha1(params, KEY)}
-print headers
-conn.request("GET",URL + "?" + params,None, headers)
-response = conn.getresponse()
-print response.status, response.reason
-data =  response.read()
-conn.close()
-print data
-
-Example python job submission parameter generation
---------------------------------------------------
-import base64
-import hmac
-import sha
-import httplib, urllib
-import sys
-import time
-import os
-from popen2 import popen3
-
-def hmac_sha1(data, key):

-USER = stdout.read().strip()
-f = open(os.path.expanduser("~/.ssh/hadoop_key"))
-KEY = f.read().strip()
-f.close()
-if len(sys.argv) > 1:
-  params = sys.argv[1]
-else:
-  params = ""
-timestamp = long(time.time()*1000)
-params = params + "&user=%s×tamp=%d" % (USER,timestamp)

-/**
- * A {@link TaskScheduler} that 
- * provides the following features: 
- * The purpose of this scheduler is to allow users to increase and decrease
- * their queue priorities continuosly to meet the requirements of their
- * current workloads. The scheduler is aware of the current demand and makes
- * it more expensive to boost the priority under peak usage times. Thus
- * users who move their workload to low usage times are rewarded with
- * discounts. Priorities can only be boosted within a limited quota.
- * All users are given a quota or a budget which is deducted periodically
- * in configurable accounting intervals. How much of the budget is
- * deducted is determined by a per-user spending rate, which may
- * be modified at any time directly by the user. The cluster slots
- * share allocated to a particular user is computed as that users
- * spending rate over the sum of all spending rates in the same accounting
- * period.
- *
- * This scheduler has been designed as a meta-scheduler on top of 
- * existing MapReduce schedulers, which are responsible for enforcing
- * shares computed by the dynamic scheduler in the cluster.

-\author{}

-\section{Introduction}
-
-The Hadoop Fair Scheduler started as a simple means to share MapReduce clusters. Over time, it has grown in functionality to support hierarchical scheduling, preemption, and multiple ways of organizing and weighing jobs. This document explains the goals and features of the Fair Scheduler and its internal design.
-
-\section{Fair Scheduler Goals}
-
-The Fair Scheduler was designed with four main goals:
-\begin{enumerate}
-  \item Run small jobs quickly even if they are sharing a cluster with large jobs. Unlike Hadoop's built-in FIFO scheduler, fair scheduling lets small jobs make progress even if a large job is running, without starving the large job.
-  \item Provide guaranteed service levels to ``production" jobs, to let them run alongside experimental jobs in a shared cluster.
-  \item Be simple to administer and configure. The scheduler should do something reasonable ``out of the box," and users should only need to configure it as they discover that they want to use more advanced features.
-  \item Support reconfiguration at runtime, without requiring a cluster restart.
-\end{enumerate}
-
-\section{Scheduler Features}
-
-This section provides a quick overview of the features of the Fair Scheduler. A detailed usage guide is available in the Hadoop documentation in {\tt build/docs/fair\_scheduler.html}.
-
-\subsection{Pools}
-
-The Fair Scheduler groups jobs into ``pools" and performs fair sharing between these pools. Each pool can use either FIFO or fair sharing to schedule jobs internal to the pool. The pool that a job is placed in is determined by a JobConf property, the ``pool name property". By default, this is {\tt mapreduce.job.user.name}, so that there is one pool per user. However, different properties can be used, e.g.~{\tt group.name} to have one pool per Unix group.
-
-A common trick is to set the pool name property to an unused property name such as {\tt pool.name} and make this default to {\tt mapreduce.job.user.name}, so that there is one pool per user but it is also possible to place jobs into ``special" pools by setting their {\tt pool.name} directly. The {\tt mapred-site.xml} snippet below shows how to do this:
-
-\begin{verbatim}
-
-  mapred.fairscheduler.poolnameproperty
-  pool.name
-
-
-
-  pool.name
-  ${mapreduce.job.user.name}
-
-\end{verbatim}
-
-\subsection{Minimum Shares}
-
-Normally, active pools (those that contain jobs) will get equal shares of the map and reduce task slots in the cluster. However, it is also possible to set a \emph{minimum share} of map and reduce slots on a given pool, which is a number of slots that it will always get when it is active, even if its fair share would be below this number. This is useful for guaranteeing that production jobs get a certain desired level of service when sharing a cluster with non-production jobs. Minimum shares have three effects:
-\begin{enumerate}
-  \item The pool's fair share will always be at least as large as its minimum share. Slots are taken from the share of other pools to achieve this. The only exception is if the minimum shares of the active pools add up to more than the total number of slots in the cluster; in this case, each pool's share will be scaled down proportionally.
-  \item Pools whose running task count is below their minimum share get assigned slots first when slots are available.
-  \item It is possible to set a \emph{preemption timeout} on the pool after which, if it has not received enough task slots to meet its minimum share, it is allowed to kill tasks in other jobs to meet its share. Minimum shares with preemption timeouts thus act like SLAs.
-\end{enumerate}
-
-Note that when a pool is inactive (contains no jobs), its minimum share is not ``reserved" for it -- the slots are split up among the other pools.
-
-\subsection{Preemption}
-
-As explained above, the scheduler may kill tasks from a job in one pool in order to meet the minimum share of another pool. We call this preemption, although this usage of the word is somewhat strange given the normal definition of preemption as pausing; really it is the \emph{job} that gets preempted, while the task gets killed. The feature explained above is called \emph{min share preemption}. In addition, the scheduler supports \emph{fair share preemption}, to kill tasks when a pool's fair share is not being met. Fair share preemption is much more conservative than min share preemption, because pools without min shares are expected to be non-production jobs where some amount of unfairness is tolerable. In particular, fair share preemption activates if a pool has been below \emph{half} of its fair share for a configurable fair share preemption timeout, which is recommended to be set fairly high (e.g. 10 minutes).
-
-In both types of preemption, the scheduler kills the most recently launched tasks from over-scheduled pools, to minimize the amount of computation wasted by preemption.
-
-\subsection{Running Job Limits}
-
-The fair scheduler can limit the number of concurrently running jobs from each user and from each pool. This is useful for limiting the amount of intermediate data generated on the cluster. The jobs that will run are chosen in order of submit time and priority. Jobs submitted beyond the limit wait for one of the running jobs to finish.
-
-\subsection{Job Priorities}
-
-Within a pool, job priorities can be used to control the scheduling of jobs, whether the pool's internal scheduling mode is FIFO or fair sharing:
-\begin{itemize}
-  \item In FIFO pools, jobs are ordered first by priority and then by submit time, as in Hadoop's default scheduler.
-  \item In fair sharing pools, job priorities are used as weights to control how much share a job gets. The normal priority corresponds to a weight of 1.0, and each level gives 2x more weight. For example, a high-priority job gets a weight of 2.0, and will therefore get 2x the share of a normal-priority job. 
-\end{itemize}
-
-\subsection{Pool Weights}
-
-Pools can be given weights to achieve unequal sharing of the cluster. For example, a pool with weight 2.0 gets 2x the share of a pool with weight 1.0.
-
-\subsection{Delay Scheduling}
-
-The Fair Scheduler contains an algorithm called delay scheduling to improve data locality. Jobs that cannot launch a data-local map task wait for some period of time before they are allowed to launch non-data-local tasks, ensuring that they will run locally if some node in the cluster has the relevant data. Delay scheduling is described in detail in Section \ref{sec:delay-scheduling}.
-
-\subsection{Administration}
-
-The Fair Scheduler includes a web UI displaying the active pools and jobs and their fair shares, moving jobs between pools, and changing job priorities.
-In addition, the Fair Scheduler's allocation file (specifying min shares and preemption timeouts for the pools) is automatically reloaded if it is modified on disk, to allow runtime reconfiguration.
-
-\section{Implementation}
-
-\subsection{Hadoop Scheduling Background}
-
-Hadoop jobs consist of a number of map and reduce \emph{tasks}. These task run in \emph{slots} on the nodes on the cluster. Each node is configured with a number of map slots and reduce slots based on its computational resources (typically one slot per core). The role of the scheduler is to assign tasks to any slots that are free.
-
-All schedulers in Hadoop, including the Fair Scheduler, inherit from the {\tt TaskScheduler} abstract class. This class provides access to a {\tt TaskTrackerManager} -- an interface to the JobTracker -- as well as a {\tt Configuration} instance. It also ask the scheduler to implement three abstract methods: the lifecycle methods {\tt start} and {\tt terminate}, and a method called {\tt assignTasks} to launch tasks on a given TaskTracker.
-Task assignment in Hadoop is reactive. TaskTrackers periodically send heartbeats to the JobTracker with their {\tt TaskTrackerStatus}, which contains a list of running tasks, the number of slots on the node, and other information. The JobTracker then calls {\tt assignTasks} on the scheduler to obtain tasks to launch. These are returned with the heartbeat response.
-
-Apart from reacting to heartbeats through {\tt assignTasks}, schedulers can also be notified when jobs have been submitted to the cluster, killed, or removed by adding listeners to the {\tt TaskTrackerManager}. The Fair Scheduler sets up these listeners in its {\tt start} method. An important role of the listeners is to initialize jobs that are submitted -- until a job is initialized, it cannot launch tasks. The Fair Scheduler currently initializes all jobs right away, but it may also be desirable to hold off initializing jobs if too many are submitted to limit memory usage on the JobTracker.
-
-Selection of tasks \emph{within} a job is mostly done by the {\tt JobInProgress} class, and not by individual schedulers. {\tt JobInProgress} exposes two methods, {\tt obtainNewMapTask} and {\tt obtainNewReduceTask}, to launch a task of either type. Both methods may either return a {\tt Task} object or {\tt null} if the job does not wish to launch a task. Whether a job wishes to launch a task may change back and forth during its lifetime. Even after all tasks in the job have been started, the job may wish to run another task for speculative execution. In addition, if the node containing a map task failed, the job will wish to re-run it to rebuild its output for use in the reduce tasks. Schedulers may therefore need to poll multiple jobs until they find one with a task to run.
-
-Finally, for map tasks, an important scheduling criterion is data locality: running the task on a node or rack that contains its input data. Normally, {\tt JobInProgress.obtainNewMapTask} returns the ``closest" map task to a given node. However, to give schedulers slightly more control over data locality, there is also a version of {\tt obtainNewMapTask} that allow the scheduler to cap the level of non-locality allowed for the task (e.g.~request a task only on the same node, or {\tt null} if none is available). The Fair Scheduler uses this method with an algorithm called delay scheduling (Section \ref{sec:delay-scheduling}) to optimize data locality.
-
-\subsection{Fair Scheduler Basics}
-
-At a high level, the Fair Scheduler uses hierarchical scheduling to assign tasks. First it selects a pool to assign a task to according to the fair sharing algorithm in Section \ref{sec:fair-sharing-alg}. Then it asks the pool obtain a task. The pool chooses among its jobs according to its internal scheduling order (FIFO or fair sharing).
-
-In fact, because jobs might not have tasks to launch ({\tt obtainNew(Map|Reduce)Task} can return null), the scheduler actually establishes an ordering on jobs and asks them for tasks in turn. Within a pool, jobs are sorted either by priority and start time (for FIFO) or by distance below fair share. If the first job in the ordering does not have a task to launch, the pool will ask the second, third, etc jobs. Pools themselves are sorted by distance below min share and fair share, so if the first pool does not have any jobs that can launch tasks, the second pool is asked, etc. This makes it straightforward to implement features like delay scheduling (Section \ref{sec:delay-scheduling}) that may cause jobs to ``pass" on a slot.
-
-Apart from the assign tasks code path, the Fair Scheduler also has a periodic update thread that calls {\tt update} every few seconds. This thread is responsible for recomputing fair shares to display them on the UI (Section \ref{sec:fair-share-computation}), checking whether jobs need to be preempted (Section \ref{sec:preemption}), and checking whether the allocations file has changed to reload pool allocations (through {\tt PoolManager}).
-
-\subsection{The {\tt Schedulable} Class}
-
-To allow the same fair sharing algorithm to be used both between pools and within a pool, the Fair Scheduler uses an abstract class called {\tt Schedulable} to represent both pools and jobs. Its subclasses for these roles are {\tt PoolSchedulable} and {\tt JobSchedulable}. A {\tt Schedulable} is responsible for three roles:
-\begin{enumerate}
-  \item It can be asked to obtain a task through {\tt assignTask}. This may return {\tt null} if the {\tt Schedulable} has no tasks to launch.
-  \item It can be queried for information about the pool/job to use in scheduling, such as:
-  \begin{itemize}
-    \item Number of running tasks.
-    \item Demand (number of tasks the {\tt Schedulable} \emph{wants} to run; this is equal to number of running tasks + number of unlaunched tasks).
-    \item Min share assigned through config file.
-    \item Weight (for fair sharing).
-    \item Priority and start time (for FIFO scheduling).
-  \end{itemize}
-  \item It can be assigned a fair share through {\tt setFairShare}.
-\end{enumerate}
-
-There are separate {\tt Schedulable}s for map and reduce tasks, to make it possible to use the same algorithm on both types of tasks.
-
-\subsection{Fair Sharing Algorithm}
-\label{sec:fair-sharing-alg}
-
-A simple way to achieve fair sharing is the following: whenever a slot is available, assign it to the pool that has the fewest running tasks. This will ensure that all pool get an equal number of slots, unless a pool's demand is less than its fair share, in which case the extra slots are divided evenly among the other pools. Two features of the Fair Scheduler complicate this algorithm a little:
-\begin{itemize}
-  \item Pool weights mean that some pools should get more slots than others. For example, a pool with weight 2 should get 2x more slots than a pool with weight 1. This is accomplished by changing the scheduling rule to ``assign the slot to the pool whose value of $runningTasks/weight$ is smallest."
-  \item Minimum shares mean that pools below their min share should get slots first. When we sort pools to choose which ones to schedule next, we place pools below their min share ahead of pools above their min share. We order the pools below their min share by how far they are below it as a percentage of the share.
-\end{itemize}
-
-This fair sharing algorithm is implemented in {\tt FairShareComparator} in the {\tt SchedulingAlgorithms} class. The comparator orders jobs by distance below min share and then by $runningTasks/weight$.
-
-\subsection{Preemption}
-\label{sec:preemption}
-
-To determine when to preempt tasks, the Fair Schedulers maintains two values for each {\tt PoolSchedulable}: the last time when the pool was at its min share, and the last time when the pool was at half its fair share. These conditions are checked periodically by the update thread in {\tt FairScheduler.updatePreemptionVariables}, using the methods {\tt isStarvedForMinShare} and {\tt isStarvedForFairShare}. These methods also take into account the demand of the pool, so that a pool is not counted as starving if its demand is below its min/fair share but is otherwise met.
-
-When preempting tasks, the scheduler kills the most recently launched tasks from over-scheduled pools. This minimizes the amount of computation wasted by preemption and ensures that all jobs can eventually finish (it is as if the preempted jobs just never got their last few slots). The tasks are chosen and preempted in {\tt preemptTasks}.
-
-Note that for min share preemption, it is clear when a pool is below its min share because the min share is given as a number of slots, but for fair share preemption, we must be able to compute a pool's fair share to determine when it is being starved. This computation is trickier than dividing the number of slots by the number of pools due to weights, min shares and demands. Section \ref{sec:fair-share-computation} explains how fair shares are computed.
-
-\subsection{Fair Share Computation}
-\label{sec:fair-share-computation}
-
-The scheduling algorithm in Section \ref{sec:fair-sharing-alg} achieves fair shares without actually needing to compute pools' numerical shares beforehand. However, for preemption and for displaying shares in the Web UI, we want to know what a pool's fair share is even if the pool is not currently at its share. That is, we want to know how many slots the pool \emph{would} get if we started with all slots being empty and ran the algorithm in Section \ref{sec:fair-sharing-alg} until we filled them.
-One way to compute these shares would be to simulate starting out with empty slots and calling {\tt assignTasks} repeatedly until they filled, but this is expensive, because each scheduling decision takes $O(numJobs)$ time and we need to make $O(numSlots)$ decisions.
-
-To compute fair shares efficiently, the Fair Scheduler includes an algorithm based on binary search in {\tt SchedulingAlgorithms.computeFairShares}. This algorithm is based on the following observation. If all slots had been assigned according to weighted fair sharing respecting pools' demands and min shares, then there would exist a ratio $r$ such that:
-\begin{enumerate}
-  \item Pools whose demand $d_i$ is less than $r w_i$ (where $w_i$ is the weight of the pool) are assigned $d_i$ slots.
-  \item Pools whose min share $m_i$ is more than $r w_i$ are assigned $\min(m_i, d_i)$ slots.
-  \item All other pools are assigned $r w_i$ slots.
-  \item The pools' shares sum up to the total number of slots $t$.
-\end{enumerate}
-
-The Fair Scheduler uses binary search to compute the correct $r$. We define a function $f(r)$ as the number of slots that would be used for a given $r$ if conditions 1-3 above were met, and then find a value of $r$ that makes $f(r)=t$. More precisely, $f(r)$ is defined as:
-$$f(r) = \sum_i{\min(d_i, \max(r w_i, m_i)).}$$
-
-Note that $f(r)$ is increasing in $r$ because every term of the sum is increasing, so the equation $f(r) = t$ can be solved by binary search. We choose 0 as a lower bound of our binary search because with $r=0$, only min shares are assigned. (An earlier check in {\tt computeFairShares} checks whether the min shares add up to more than the total number of slots, and if so, computes fair shares by scaling down the min shares proportionally and returns.) To compute an upper bound for the binary search, we try $r=1,2,4,8,\dots$ until we find a value large enough that either more than $t$ slots are used or all pools' demands are met (in case the demands added up to less than $t$).
-
-The steps of the algorithm are explained in detail in {\tt SchedulingAlgorithms.java}.
-
-This algorithm runs in time $O(NP)$, where $N$ is the number of jobs/pools and $P$ is the desired number of bits of precision in the computed values (number of iterations of binary search), which we've set to 25. It thus scales linearly in the number of jobs and pools.
-
-\subsection{Running Job Limits}
-
-Running job limits are implemented by marking jobs as not runnable if there are too many jobs submitted by the same user or pool. This is done in {\tt FairScheduler.updateRunnability}. A job that is not runnable declares its demand as 0 and always returns {\tt null} from {\tt assignTasks}.
-
-\subsection{Delay Scheduling}
-\label{sec:delay-scheduling}
-
-In Hadoop, running map tasks on the nodes or racks that contain their input data is critical for performance, because it avoids shipping the data over the network. However, always assigning slots to the first job in order of pool shares and in-pool ordering (the ``head-of-line job") can sometimes lead to poor locality:
-\begin{itemize}
-  \item If the head-of-line job is small, the chance of it having data on the node that a heartbeat was received from is small. Therefore, locality would be poor in a small-job workload if we always assigned slots to the head-of-line job.
-  \item When fair sharing is used, there is a strong bias for a job to be reassigned into a slot that it just finished a task in, because when it finishes the task, the job falls below its fair share. This can mean that jobs have a difficult time running in slots that other jobs have taken and thus achieve poor locality.
-\end{itemize}
-
-To deal with both of these situations, the Fair Scheduler can sacrifice fairness temporarily to improve locality through an algorithm called delay scheduling. If the head-of-line job cannot launch a local task on the TaskTracker that sent a heartbeat, then it is skipped, and other running jobs are looked at in order of pool shares and in-pool scheduling rules to find a job with a local task. However, if the head-of-line job has been skipped for a sufficiently long time, it is allowed to launch rack-local tasks. Then, if it is skipped for a longer time, it is also allowed to launch off-rack tasks. These skip times are called locality delays. Delays of a few seconds are sufficient to drastically increase locality.
-
-The Fair Scheduler allows locality delays to be set through {\tt mapred-site.xml} or to be turned off by setting them to zero. However, by default, it computes the delay automatically based on the heartbeat interval of the cluster. The delay is set to 1.5x the heartbeat interval.
-
-When a job that has been allowed to launch non-local tasks ends up launching a local task again, its ``locality level" resets and it must wait again before launching non-local tasks. This is done so that a job that gets ``unlucky" early in its lifetime does not continue to launch non-local tasks throughout its life.
-
-Delay scheduling is implemented by keeping track of two variables on each job: the locality level of the last map it launched (0 for node-local, 1 for rack-local and 2 for off-rack) and the time it has spent being skipped for a task. These are kept in a {\tt JobInfo} structure associated with each job in {\tt FairScheduler.java}. Whenever a job is asked for tasks, it checks the locality level it is allowed to launch them at through {\tt FairScheduler.getAllowedLocalityLevel}. If it does not launch a task, it is marked as ``visited" on that heartbeat by appending itself to a {\tt visited} job list that is passed around between calls to {\tt assignTasks} on the same heartbeat. Jobs that are visited on a heartbeat but do not launch any tasks during it are considered as skipped for the time interval between this heartbeat and the next. Code at the beginning of {\tt FairScheduler.assignTasks} increments the wait time of each skipped job by the time elapsed since the last heartbeat. Once a job has been skipped for more than the locality delay, {\tt getAllowedLocalityLevel} starts returning higher locality so that it is allowed to launch less-local tasks. Whenever the job launches a task, its wait time is reset, but we remember the locality level of the launched task so that the job is allowed to launch more tasks at this level without further waiting.
-
-\subsection{Locking Order}
-
-Fair Scheduler data structures can be touched by several threads. Most commonly, the JobTracker invokes {\tt assignTasks}. This happens inside a block of code where the JobTracker has locked itself already. Therefore, to prevent deadlocks, we always ensure that \emph{if both the FairScheduler and the JobTracker must be locked, the JobTracker is locked first}. Other threads that can lock the FairScheduler include the update thread and the web UI.
-
-\subsection{Unit Tests}
-
-The Fair Scheduler contains extensive unit tests using mock {\tt TaskTrackerManager}, {\tt JobInProgress}, {\tt TaskInProgress}, and {\tt Schedulable} objects. Scheduler tests are in {\tt TestFairScheduler.java}. The {\tt computeFairShares} algorithm is tested separately in {\tt TestComputeFairShares.java}. All tests use accelerated time via a fake {\tt Clock} class.

-The following table lists some key source files in the Fair Scheduler:
-
-\begin{center}
-\begin{tabular}{|l|p{0.7\columnwidth}|}
-  \hline
-  {\bf File} & {\bf Contents} 
-  \\ \hline
-  {\tt FairScheduler.java} & Scheduler entry point. Also contains update thread, and logic for preemption, delay scheduling, and running job limits.
-  \\ \hline
-  {\tt Schedulable.java} & Definition of the {\tt Schedulable} class. Extended by {\tt JobSchedulable} and {\tt PoolSchedulable}.
-  \\ \hline
-  {\tt SchedulingAlgorithms.java} & Contains FIFO and fair sharing comparators, as well as the {\tt computeFairShares} algorithm in Section \ref{sec:fair-share-computation}.
-  \\ \hline
-  {\tt PoolManager.java} & Reads pool properties from the allocation file and maintains a collection of {\tt Pool} objects. Pools are created on demand.
-  \\ \hline
-  {\tt Pool.java} & Represents a pool and stores its map and reduce {\tt Schedulables}.
-  \\ \hline
-  {\tt FairSchedulerServlet.java} & Implements the scheduler's web UI.
-  \\ \hline
-  {\tt FairSchedulerEventLog.java} & An easy-to-parse event log for debugging. Must be enabled through {\tt mapred.fairscheduler.eventlog.enabled}.
-  If enabled, logs are placed in {\tt \$HADOOP\_LOG\_DIR/fairscheduler}.
-  \\ \hline
-  {\tt TaskSelector.java} & A pluggable class responsible for picking tasks within a job. Currently, {\tt DefaultTaskSelector} delegates to {\tt JobInProgress}, but this would be a useful place to experiment with new algorithms for speculative execution and locality.
-  \\ \hline
-  {\tt LoadManager.java} & A pluggable class responsible for determining when to launch more tasks on a TaskTracker. Currently, {\tt CapBasedLoadManager} uses slot counts, but this would be a useful place to experiment with scheduling based on machine load.
-  \\ \hline
-  {\tt WeightAdjuster.java} & A pluggable class responsible for setting job weights. An example, {\tt NewJobWeightBooster}, is provided, which increases weight temporarily for new jobs.

-/**
- * A Schedulable represents an entity that can launch tasks, such as a job
- * or a pool. It provides a common interface so that algorithms such as fair
- * sharing can be applied both within a pool and across pools. There are 
- * currently two types of Schedulables: JobSchedulables, which represent a
- * single job, and PoolSchedulables, which allocate among jobs in their pool.
- * 
- * Separate sets of Schedulables are used for maps and reduces. Each pool has
- * both a mapSchedulable and a reduceSchedulable, and so does each job.
- * 
- * A Schedulable is responsible for three roles:
- * 1) It can launch tasks through assignTask().
- * 2) It provides information about the job/pool to the scheduler, including:
- *    - Demand (maximum number of tasks required)
- *    - Number of currently running tasks
- *    - Minimum share (for pools)
- *    - Job/pool weight (for fair sharing)
- *    - Start time and priority (for FIFO)
- * 3) It can be assigned a fair share, for use with fair scheduling.
- * 
- * Schedulable also contains two methods for performing scheduling computations:
- * - updateDemand() is called periodically to compute the demand of the various
- *   jobs and pools, which may be expensive (e.g. jobs must iterate through all
- *   their tasks to count failed tasks, tasks that can be speculated, etc).
- * - redistributeShare() is called after demands are updated and a Schedulable's
- *   fair share has been set by its parent to let it distribute its share among
- *   the other Schedulables within it (e.g. for pools that want to perform fair
- *   sharing among their jobs).

-   * Given a set of Schedulables and a number of slots, compute their weighted

-   * be set beforehand. We compute the fairest possible allocation of shares 
-   * to the Schedulables that respects their min shares and demands.
-   * 
-   * To understand what this method does, we must first define what weighted
-   * fair sharing means in the presence of minimum shares and demands. If there
-   * were no minimum shares and every Schedulable had an infinite demand (i.e.
-   * could launch infinitely many tasks), then weighted fair sharing would be
-   * achieved if the ratio of slotsAssigned / weight was equal for each
-   * Schedulable and all slots were assigned. Minimum shares and demands add
-   * two further twists:
-   * - Some Schedulables may not have enough tasks to fill all their share.
-   * - Some Schedulables may have a min share higher than their assigned share.
-   * 
-   * To deal with these possibilities, we define an assignment of slots as
-   * being fair if there exists a ratio R such that:
-   * - Schedulables S where S.demand < R * S.weight are assigned share S.demand
-   * - Schedulables S where S.minShare > R * S.weight are given share S.minShare
-   * - All other Schedulables S are assigned share R * S.weight
-   * - The sum of all the shares is totalSlots.
-   * 
-   * We call R the weight-to-slots ratio because it converts a Schedulable's
-   * weight to the number of slots it is assigned.
-   * 
-   * We compute a fair allocation by finding a suitable weight-to-slot ratio R.
-   * To do this, we use binary search. Given a ratio R, we compute the number
-   * of slots that would be used in total with this ratio (the sum of the shares
-   * computed using the conditions above). If this number of slots is less than
-   * totalSlots, then R is too small and more slots could be assigned. If the
-   * number of slots is more than totalSlots, then R is too large. 
-   * 
-   * We begin the binary search with a lower bound on R of 0 (which means that
-   * all Schedulables are only given their minShare) and an upper bound computed
-   * to be large enough that too many slots are given (by doubling R until we
-   * either use more than totalSlots slots or we fulfill all jobs' demands).
-   * The helper method slotsUsedWithWeightToSlotRatio computes the total number
-   * of slots used with a given value of R.
-   * 
-   * The running time of this algorithm is linear in the number of Schedulables,
-   * because slotsUsedWithWeightToSlotRatio is linear-time and the number of
-   * iterations of binary search is a constant (dependent on desired precision).

-    

-      Purpose
-      
-      
This document describes the Capacity Scheduler, a pluggable 
-      MapReduce scheduler for Hadoop which provides a way to share 
-      large clusters.

-    

-    
-    

-      Features
-      
-      
The Capacity Scheduler supports the following features:
 
-      
    
-        
  • 
-          Multiple queues, possibly hierarchical/recursive, where a job is
-          submitted to a queue.
-        
    • 
-        
  • 
-          Queues are allocated a fraction of the capacity of the grid in the 
-          sense that a certain capacity of resources will be at their 
-          disposal. All jobs submitted to a queue will have access to the 
-          capacity allocated to the queue.
-        
    • 
-        
  • 
-          Free resources can be allocated to any queue beyond it's capacity. 
-          When there is demand for these resources from queues running below 
-          capacity at a future point in time, as tasks scheduled on these 
-          resources complete, they will be assigned to jobs on queues 
-          running below the capacity.
-        
    • 
-        
  • 
-          Queues optionally support job priorities (disabled by default).
-        
    • 
-        
  • 
-          Within a queue, jobs with higher priority will have access to the 
-          queue's resources before jobs with lower priority. However, once a 
-          job is running, it will not be preempted for a higher priority job,
-          though new tasks from the higher priority job will be 
-          preferentially scheduled.
-        
    • 
-        
  • 
-          In order to prevent one or more users from monopolizing its 
-          resources, each queue enforces a limit on the percentage of 
-          resources allocated to a user at any given time, if there is 
-          competition for them.  
-        
    • 
-        
  • 
-          Queues can use idle resources of other queues. In order to prevent
-          monopolizing of resources by particular queues, each queue can be
-          set a cap on the maximum number of resources it can expand to in
-          the presence of idle resources in other queues of the cluster.
-        
    • 
-        
  • 
-          Support for memory-intensive jobs, wherein a job can optionally 
-          specify higher memory-requirements than the default, and the tasks 
-          of the job will only be run on TaskTrackers that have enough memory 
-          to spare.
-        
    • 
-        
  • 
-          Support for refreshing/reloading some of the queue-properties
-          without restarting the JobTracker, taking advantage of the
-          
-          queue-refresh feature in the framework.

-    

-      Picking a Task to Run
-      
-      
Note that many of these steps can be, and will be, enhanced over time
-      to provide better algorithms.

-      
-      
Whenever a TaskTracker is free, the Capacity Scheduler picks 
-      a queue which has most free space (whose ratio of # of running slots to 
-      capacity is the lowest).

-      
-      
Once a queue is selected, the Scheduler picks a job in the queue. Jobs
-      are sorted based on when they're submitted and their priorities (if the 
-      queue supports priorities). Jobs are considered in order, and a job is 
-      selected if its user is within the user-quota for the queue, i.e., the 
-      user is not already using queue resources above his/her limit. The 
-      Scheduler also makes sure that there is enough free memory in the 
-      TaskTracker to tun the job's task, in case the job has special memory
-      requirements.

-      
-      
Once a job is selected, the Scheduler picks a task to run. This logic 
-      to pick a task remains unchanged from earlier versions.
 
-
-      

-        Scheduling Tasks Considering Memory Requirements
-      
-        

-        The Capacity Scheduler supports scheduling of tasks on a
-        TaskTracker based on a job's virtual memory requirements and 
-        the availability
-        of enough virtual memory on the TaskTracker node. By doing so, it
-        simplifies the virtual memory monitoring function on the 
-        TaskTracker node, described in the section on 
-        
-        Monitoring Task Memory Usage in the Cluster Setup guide. 
-        Refer to that section for more details on how memory for 
-        MapReduce tasks is handled.
-        

-        
-        

-        Virtual memory based task scheduling uses the same parameters as
-        the memory monitoring function of the TaskTracker, and is enabled
-        along with virtual memory monitoring. When enabled, the scheduler
-        ensures that a task is scheduled on a TaskTracker only when the
-        virtual memory required by the map or reduce task can be assured 
-        by the TaskTracker. That is, the task is scheduled only if the 
-        following constraint is satisfied:

-        
-        Job's mapreduce.{map|reduce}.memory.mb of the job <=
-          total virtual memory for all map or reduce tasks on the TaskTracker -
-            total virtual memory required for all running map or reduce tasks 
-            on the TaskTracker
-        

-        

-        
-        

-        When a task at the front of the scheduler's queue cannot be scheduled
-        on a TaskTracker due to insufficient memory, the scheduler creates
-        a virtual reservation for this task. This can continue
-        for all pending tasks on a job, subject to other capacity constraints.
-        Once all tasks are either scheduled or have reservations, the 
-        scheduler will proceed to schedule other jobs's tasks that are not 
-        necessarily at the front of the queue, but meet memory constraints 
-        of the TaskTracker.
-        By following this reservation procedure of reserving just enough
-        TaskTrackers, the scheduler balances between not starving jobs with 
-        high memory requirements and under-utilizing cluster resources.
-        

-
-        

-        Tasks of jobs that require more virtual memory than the
-        per slot mapreduce.cluster.{map|reduce}memory.mb
-        value, are treated as occupying more than one slot, and account
-        for a corresponding increased capacity usage for their queue.
-        The number of slots they occupy is determined as:

-        
-        Number of slots for a task = mapreduce.{map|reduce}.memory.mb / 
-        mapreduce.cluster.{map|reduce}memory.mb
-        

-        However, special tasks run by the framework like setup 
-        and cleanup tasks do not count for more than 1 slot, 
-        irrespective of their job's memory requirements.
-

-      Installation
-      
-        
The Capacity Scheduler is available as a JAR file in the Hadoop
-        tarball under the contrib/capacity-scheduler directory. The name of 
-        the JAR file would be on the lines of hadoop-*-capacity-scheduler.jar.

-        
You can also build the Scheduler from source by executing
-        ant package, in which case it would be available under
-        build/contrib/capacity-scheduler.

-        
To run the Capacity Scheduler in your Hadoop installation, you need 
-        to put it on the CLASSPATH. The easiest way is to copy the 
-        hadoop-*-capacity-scheduler.jar from 
-        to HADOOP_PREFIX/lib. Alternatively, you can modify 
-        HADOOP_CLASSPATH to include this jar, in 
-        conf/hadoop-env.sh.

-    

-
-    

-      Configuration
-
-      

-        Using the Capacity Scheduler
-        

-          To make the Hadoop framework use the Capacity Scheduler, set up
-          the following property in the site configuration:

-          
-            
-              
-              
-            
-            
-

-      

-
-      

-        Setting Up Queues
-        

-          You can define multiple, possibly hierarchical queues to which users
-          can submit jobs with the Capacity Scheduler. To define queues,
-          various properties should be set in two configuration files -
-          mapred-queues.xml
-          and
-          conf/capacity-scheduler.xml
-          .

-          
conf/capacity-scheduler.xml can be used to configure (1)
-          job-initialization-poller related properties and (2) the
-          default values for various properties in the queues

-          
conf/mapred-queues.xml contains the actual queue
-          configuration including (1) framework specific properties like ACLs
-          for controlling which users or groups have access to the queues and
-          state of the queues and (2) the scheduler specific properties for
-          each queue. If any of these scheduler specific properties are
-          missing and not configured for a queue, then the properties in
-          conf/capacity-scheduler.xml are used to set default values.
-          More details about the properties that can be configured, and their
-          semantics is mentioned below. Also, a default template for 
-          mapred-queues.xml tailored for using with
-          Capacity-scheduler can be found
-          here.

-      

-  
-      

-        Configuring Properties for Queues
-
-        
The Capacity Scheduler can be configured with several properties
-        for each queue that control the behavior of the Scheduler. As
-        described above, this scheduler specific configuration has to be in
-        the conf/mapred-queues.xml along with the rest of the
-        framework specific configuration. By
-        default, the configuration is set up for one queue, named 
-        default.

-        
To specify a property for a specific queue that is defined in the
-        mapred-queues.xml, you should set the corresponding property in a
-        <property> tag explained
-        here.
-        

-
-        
The properties defined for queues and their descriptions are
-        listed in the table below:

capacityYesContainer queues as well as leaf queuesFor a root-level container queue, this is the percentage of the
-          	number of slots in the cluster that will be available for all its
-          	immediate children together. For a root-level leaf-queue, this is
-          	the percentage of the number of slots in the cluster that will be
-          	available for all its jobs.	For a non-root level container queue,
-          	this is the percentage of the number of slots in its parent queue
-          	that will be available for all its	children together. For a
-          	non-root-level leaf queue, this	is the percentage of the number of
-          	slots in its parent queue that will be available for jobs in this
-          	queue. The sum of capacities for all children of a container queue
-          	should be less than or equal 100. The sum of capacities of all the
-          	root-level queues should be less than or equal to 100.
-            
maximum-capacityYesContainer queues as well as leaf queues
-	          A limit in percentage beyond which a non-root-level queue cannot use
-	          the capacity of its parent queue; for a root-level queue, this is
-	          the limit in percentage beyond which it cannot use the
-	          cluster-capacity. This property provides a means to limit how much
-	          excess capacity a queue can use.  It can be used to prevent queues
-	          with long running jobs from occupying more than a certain percentage
-	          of the parent-queue or the cluster, which, in the absence of
-	          pre-emption, can lead to capacity guarantees of other queues getting
-	          affected.
-	
-	          The maximum-capacity of a queue can only be greater than or equal to
-	          its capacity. By default, there is no limit for a queue. For a
-	          non-root-level queue this means it can occupy till the
-	          maximum-capacity of its parent, for a root-level queue, it means that
-	          it can occupy the whole cluster. A value of 100 implies that a queue
-	          can use the complete capacity of its parent, or the complete
-	          cluster-capacity in case of root-level-queues.
-            
supports-priorityNoLeaf queues onlyIf true, priorities of jobs will be taken into account in scheduling 
-          	decisions.
-          	
minimum-user-limit-percentYesLeaf queues onlyEach queue enforces a limit on the percentage of resources 
-          	allocated to a user at any given time, if there is competition 
-          	for them. This user limit can vary between a minimum and maximum 
-          	value. The former depends on the number of users who have submitted
-          	jobs, and the latter is set to this property value. For example, 
-          	suppose the value of this property is 25. If two users have 
-          	submitted jobs to a queue, no single user can use more than 50% 
-          	of the queue resources. If a third user submits a job, no single 
-          	user can use more than 33% of the queue resources. With 4 or more 
-          	users, no user can use more than 25% of the queue's resources. A 
-          	value of 100 implies no user limits are imposed.
-	        
maximum-initialized-jobs-per-userYesLeaf queues only
-              Maximum number of jobs which are allowed to be pre-initialized for
-              a particular user in the queue. Once a job is scheduled, i.e.
-              it starts running, then that job is not considered
-              while scheduler computes the maximum job a user is allowed to
-              initialize.
-            

-        
See  
-        this configuration file for a default configuration of queues in
-        capacity-scheduler.

-      
-   

-        Job Initialization Parameters
-        
Capacity scheduler lazily initializes the jobs before they are
-        scheduled, for reducing the memory footprint on jobtracker. 
-        Following are the parameters, by which you can control the laziness
-        of the job initialization. The following parameters can be 
-        configured in capacity-scheduler.xml:

NameDescription

-              mapred.capacity-scheduler.init-poll-interval
-            
-              Amount of time in miliseconds which is used to poll the scheduler
-              job queue to look for jobs to be initialized.
-            

-              mapred.capacity-scheduler.init-worker-threads
-            
-              Number of worker threads which would be used by Initialization
-              poller to initialize jobs in a set of queue. If number mentioned 
-              in property is equal to number of job queues then a thread is 
-              assigned jobs from one queue. If the number configured is lesser than
-              number of queues, then a thread can get jobs from more than one queue
-              which it initializes in a round robin fashion. If the number configured
-              is greater than number of queues, then number of threads spawned
-              would be equal to number of job queues.
-

-        Reviewing the Configuration of the Capacity Scheduler
-        

-          Once the installation and configuration is completed, you can review
-          it after starting the MapReduce cluster from the admin UI.
-        

-        
    
-          
  • Start the MapReduce cluster as usual.
    • 
-          
  • Open the JobTracker web UI.
    • 
-          
  • The queues you have configured should be listed under the Scheduling
-              Information section of the page.
    • 
-          
  • The properties for the queues should be visible in the Scheduling
-              Information column against each queue.
    •

-    Dynamic Priority Scheduler
-  

-  
-  
-  
-    

-      Purpose
-      
-      
This document describes the Dynamic Priority Scheduler, a pluggable 
-      MapReduce scheduler for Hadoop which provides a way to automatically manage 
-      user job QoS based on demand.

-    

-    
-    

-      Features
-      
-      
The Dynamic Priority Scheduler supports the following features:
 
-      
    
-        
  • 
-          Users may change their dedicated queue capacity at any point in time by specifying how much
-          they are willing to pay for running on a (map or reduce) slot over an allocation interval 
-          (called the spending rate).
-        
    • 
-        
  • 
-          Users are given a budget when signing up to use the Hadoop cluster. This budget may then be used
-          to run jobs requiring different QoS over time. QoS allocation intervals in the order of a few
-          seconds are supported allowing the cluster capacity allocations to follow the demand closely.
-        
    • 
-        
  • 
-          The slot capacity share given to a user is proportional to the user's spending rate
-          and inversely proportional to the spending rates of all the other users in the
-          same allocation interval. 
-        
    • 
-        
  • 
-          Preemption is supported but may be disabled.
-        
    • 
-        
  • 
-          Work conservation is supported. If a user doesn't use up the slots guaranteed
-          based on the spending rates, other users may use these slots. Whoever uses the
-          slots pays for them but nobody pays more than the spending rate they bid.
-        
    • 
-        
  • 
-          When you don't run any jobs you don't pay anything out of your budget.
-        
    • 
-

-      Problem Addressed
-      
-      
Granting users (here MapReduce job clients) capacity shares on computational clusters is
-       typically done manually by the system administrator of the Hadoop installation. If users
-       want more resources they need to renegotiate their share either with the administrator or
-       the competing users. This form of social scheduling works fine in small teams in trusted
-       environments, but breaks down in large-scale, multi-tenancy clusters with users from
-       multiple organizations.

-
-       
Even if the users are cooperative it is too complex to renegotiate
-       shares manually. If users' individual jobs vary in importance (criticality to meet certain
-       deadlines) over time and between job types severe allocation inefficiencies may occur.
-       For example, a user with a high allocated capacity may run large low-priority test jobs
-       starving out more important jobs from other users.

-
-    

-    

-      Approach
-      
To solve this problem we introduce the concept of dynamic regulated priorities. As
-      before each user is granted a certain initial quota, which we call budget. However, instead
-      of mapping the budget to a capacity share statically we allow users to specify how much
-      of their budget they are willing to spend on each job at any given point in time. We call
-      this amount the spending rate, and it is defined in units of the budget that a user is willing
-      to spend per task per allocation interval (typically < 1 minute but configurable).

-     
-      
The share allocated to a specific user is calculated as her spending rate over the spending
-      rates of all users. The scheduler is preempting tasks to guarantee the shares, but it is at the
-      same time work conserving (lets users exceed their share if no other tasks are running).
-      Furthermore, the users are only charged for the fraction of the shares they actually use, so
-      if they don't run any jobs their spending goes to 0. In this text a user is defined as the
-      owner of a queue which is the unit of Authentication, Authorization, and Accounting (AAA). If
-      there is no need to separate actual users' AAA, 
-      then they could share a queue, but that should be seen equivalent to users sharing a password, i
-      which in general is frowned upon.

-    

-    

-      Comparison to other Hadoop Schedulers
-      
Hadoop-on-demand (HOD) allows individual users to create private MapReduce clusters
-       on demand to meet their changing demands over time. Prioritization across users is still a
-       static server configuration, which in essence still relies on users being cooperative during
-       high-demand periods. Further, HOD breaks the data-local scheduling principle of
-       MapReduce and makes it more difficult to efficiently share large data sets.

-
-      
The fair-share (FAIR), and capacity (CAP) schedulers are both extensions of a simple
-      fifo queue that allow relative priorities to be set on queues. There is no notion of charging
-      or accounting on a per-use basis, and shares cannot be set by the users (they have to be
-      negotiated a-priori). So although sharing data is more efficient than with HOD, these
-      schedulers suffer from the same kind of social scheduling inefficiencies.

-
-     
Amazon Web Services (AWS) Elastic MapReduce allows virtual Hadoop clusters, which
-     read input from and writes output to S3, to be set up automatically. New instances can be
-     added to or removed from the cluster to scale the jobs up or down. Our approach is more
-     lightweight in that the virtualization is not on an OS level but on a queue level. This
-     allows us to react faster to temporary application bursts and to co-host more concurrent
-     users on each physical node. Furthermore, our approach implements a demand-based
-     pricing model whereas AWS uses fixed pricing. Furthermore, our solution works in any
-     Hadoop cluster, not only in an AWS environment. Finally, with AWS you can get up and
-     running and reconfigure within the order of 10 minutes. With this scheduler you can get
-     started and reconfigure within seconds (specified with alloc-interval below).

-    

-    

-    Implementation and Use
-    

-      Accounting
-      
Users specify a spending rate. This is the rate deducted for each active/used task slot per
-      allocation interval. The shares allocated are not calculated directly based on the user
-      specified spending rate but the effective rate that is currently being paid by users.
-      If a user has no pending or running jobs the effective spending rate for that user is set to
-      0, which assures that the user is not charged anything against her budget. If a job is
-      pending the effective rate is set to the user-specified rate to allow a share to be allocated
-      so the job can be moved from pending to active state.

-
-      
 The number of map tasks and
-      reduce tasks granted to a user in each allocation interval is based on the effective
-      spending rate in the previous allocation interval. If the user only uses a subset of the
-      allocated tasks only that subset is being charged for. Conversely, if the user is able to run
-      more tasks than the granted quota due to other tasks not running up to their full quota
-      only the spending rate times the quota is being charged for. The price signaled to users so
-      they can estimate shares accurately is based on the effective rates.

-    

-    

-      Preemption
-      
Tasks that are run in excess of the quota allocated to a particular user are subject to
-      preemption. No preemption will occur unless there are pending tasks for a user who has
-      not fulfilled her full quota. Queues (users) to preempt are picked based on the latest start-
-      time of jobs in excess of their quota.

-
-      
Excess jobs in a queue will not be killed unless all
-      excess jobs have been killed from queues with later start times. Within a queue that is
-      exceeding its quota the tasks that have run the shortest time will be killed first. All killed
-      tasks are put back in a pending state and will thus be resubmitted as soon as existing tasks
-      finish or the effective share for the queue goes up, e.g. because other users' jobs finish.
-      The preemption interval may be set equal to the scheduling interval, a longer interval, or
-      0 in which case no preemption (task killing) is done.

-    

-    

-      Security
-      
If any user can impersonate any other user or if any user can submit to any queue, the
-      economic incentives of the mechanism in the scheduler breaks down and the problem of
-      social scheduling and free-riding users comes back. Hence, stronger authentication and
-      authorization is required in this scheduler compared to the other schedulers. Since the
-      authz mechanisms are still being worked out in Hadoop we implemented a simple shared
-      secret signature based protocol inspired by the AWS query (REST) API authentication
-      used for EC2 services.

-
-      
Simple guards against replay attacks and clock/nonce
-      synchronization are also available but the main idea is to require that users prove to have
-      a secret key to be allowed to submit jobs or control queue spending rates. There are
-      currently two roles implemented, users and administrators. In general users have access
-      to information such as the current price (aggregate spending rates of active queues) of the
-      cluster and their own queue settings and usage, and can change the spending rate of their
-      queue. Admin users may also add budgets to queues, create and remove queues, and get
-      detailed usage info from all queues. 

-
-      
The basic authentication model relies on the clients
-      calculating a HMAC/SHA1 signature across their request input as well as a timestamp
-      and their user name, using their secret key. The server looks up the user's secret key in an
-      acl and determines the role granted after verifying that the signature is ok. For the REST
-      API discussed next the signature is passed in the standard HTTP Authorization header
-      and for the job submission protocol it is carried in a job configuration parameter
-      (mapred.job.signature).

-
-     
If stronger authentication protocols (asynchronous keys) are developed for Hadoop at
-     least the job submission protocol will be adopted to use it.

-    

-    

-      Control
-      
The job tracker installs a servlet accepting signed HTTP GETs and returning well-formed
-      XML responses. The servlet is installed in the scheduler context (like the fair-share
-      scheduler UI)

-      
It is installed at [job tracker URL]/scheduler

Example Request to set the spending rate

-    
-  http://myhost:50030/scheduler?setSpending=0.01&queue=myqueue
-  
The Authorization header is used for signing

-
-  
The signature is created akin to the AWS Query Authentication scheme

-  HMAC_SHA1("[query path]&user=[user]&timestamp=[timestamp]", key)
-
-  
For the servlet operations query path is everything that comes after /scheduler?
-     in the url. For job submission the query path is just the empty string "".

-   
Job submissions also need to set the following job properties:

-
-  
-   -Dmapred.job.timestamp=[ms epoch time] 
-   -Dmapred.job.signature=[signature as above] 
-   -Dmapreduce.job.queue.name=[queue]
-  
Note queue must match the user submitting the job.

-    Fair Scheduler
-  

-  
-
-    

-      Purpose
-
-      
This document describes the Fair Scheduler, a pluggable
-        MapReduce scheduler for Hadoop which provides a way to share
-        large clusters.

-    

-
-    

-      Introduction
-      
Fair scheduling is a method of assigning resources to jobs
-        such that all jobs get, on average, an equal share of resources
-        over time. When there is a single job running, that job uses the
-        entire cluster. When other jobs are submitted, tasks slots that
-        free up are assigned to the new jobs, so that each job gets
-        roughly the same amount of CPU time. Unlike the default Hadoop
-        scheduler, which forms a queue of jobs, this lets short jobs finish
-        in reasonable time while not starving long jobs. It is also an easy
-        way to share a cluster between multiple of users.
-        Fair sharing can also work with job priorities - the priorities are
-        used as weights to determine the fraction of total compute time that
-        each job gets.
-      

-      

-        The fair scheduler organizes jobs into pools, and 
-        divides resources fairly between these pools. By default, there is a 
-        separate pool for each user, so that each user gets an equal share 
-        of the cluster. It is also possible to set a job's pool based on the
-        user's Unix group or any jobconf property. 
-        Within each pool, jobs can be scheduled using either fair sharing or 
-        first-in-first-out (FIFO) scheduling.
-      

-      

-        In addition to providing fair sharing, the Fair Scheduler allows
-        assigning guaranteed minimum shares to pools, which is useful
-        for ensuring that certain users, groups or production applications
-        always get sufficient resources. When a pool contains jobs, it gets
-        at least its minimum share, but when the pool does not need its full
-        guaranteed share, the excess is split between other pools.
-      

-      

-        If a pool's minimum share is not met for some period of time, the
-        scheduler optionally supports preemption of jobs in other
-        pools. The pool will be allowed to kill tasks from other pools to make
-        room to run. Preemption can be used to guarantee
-        that "production" jobs are not starved while also allowing
-        the Hadoop cluster to also be used for experimental and research jobs.
-        In addition, a pool can also be allowed to preempt tasks if it is
-        below half of its fair share for a configurable timeout (generally
-        set larger than the minimum share preemption timeout).
-        When choosing tasks to kill, the fair scheduler picks the
-        most-recently-launched tasks from over-allocated jobs, 
-        to minimize wasted computation.
-        Preemption does not cause the preempted jobs to fail, because Hadoop
-        jobs tolerate losing tasks; it only makes them take longer to finish.
-      

-      

-        The Fair Scheduler can limit the number of concurrent
-        running jobs per user and per pool. This can be useful when a 
-        user must submit hundreds of jobs at once, or for ensuring that
-        intermediate data does not fill up disk space on a cluster when too many
-        concurrent jobs are running.
-        Setting job limits causes jobs submitted beyond the limit to wait
-        until some of the user/pool's earlier jobs finish.
-        Jobs to run from each user/pool are chosen in order of priority and then
-        submit time.
-      

-      

-        Finally, the Fair Scheduler can limit the number of concurrent
-        running tasks per pool. This can be useful when jobs have a
-        dependency on an external service like a database or web
-        service that could be overloaded if too many map or reduce
-        tasks are run at once.

-        To run the fair scheduler in your Hadoop installation, you need to put
-        it on the CLASSPATH. The easiest way is to copy the 
-        hadoop-*-fairscheduler.jar from
-        HADOOP_PREFIX/build/contrib/fairscheduler to HADOOP_PREFIX/lib.
-        Alternatively you can modify HADOOP_CLASSPATH to include this jar, in
-        HADOOP_CONF_DIR/hadoop-env.sh
-      

-      

-       You will also need to set the following property in the Hadoop config 
-       file  HADOOP_CONF_DIR/mapred-site.xml to have Hadoop use 
-       the fair scheduler:
-      

-
-<property>
-  <name>mapreduce.jobtracker.taskscheduler</name>
-  <value>org.apache.hadoop.mapred.FairScheduler</value>
-</property>
-
-      

-        Once you restart the cluster, you can check that the fair scheduler 
-        is running by going to http://<jobtracker URL>/scheduler 
-        on the JobTracker's web UI. A "job scheduler administration" page should 
-        be visible there. This page is described in the Administration section.
-      

-      

-        If you wish to compile the fair scheduler from source, run  ant 
-        package in your HADOOP_PREFIX directory. This will build
-        build/contrib/fair-scheduler/hadoop-*-fairscheduler.jar.
-      

-    

-    
-    

-      Configuration
-      

-        The Fair Scheduler contains configuration in two places -- algorithm
-        parameters are set in HADOOP_CONF_DIR/mapred-site.xml, while 
-        a separate XML file called the allocation file, 
-        located by default in
-        HADOOP_CONF_DIR/fair-scheduler.xml, is used to configure
-        pools, minimum shares, running job limits and preemption timeouts.
-        The allocation file is reloaded periodically at runtime, 
-        allowing you to change pool settings without restarting 
-        your Hadoop cluster.
-      

-      

-        For a minimal installation, to just get equal sharing between users,
-        you will not need to edit the allocation file.
-      

-      

-      Scheduler Parameters in mapred-site.xml
-        

-          The following parameters can be set in mapred-site.xml
-          to affect the behavior of the fair scheduler:
-

NameDescription

-            mapred.fairscheduler.sizebasedweight
-          
-            Take into account job sizes in calculating their weights for fair 
-            sharing. By default, weights are only based on job priorities. 
-            Setting this flag to true will make them based on the size of the 
-            job (number of tasks needed) as well,though not linearly 
-            (the weight will be proportional to the log of the number of tasks 
-            needed). This lets larger jobs get larger fair shares while still 
-            providing enough of a share to small jobs to let them finish fast. 
-            Boolean value, default: false.
-          

-            mapred.fairscheduler.preemption.only.log
-          
-            This flag will cause the scheduler to run through the preemption
-            calculations but simply log when it wishes to preempt a task,
-            without actually preempting the task. 
-            Boolean property, default: false.
-            This property can be useful for
-            doing a "dry run" of preemption before enabling it to make sure
-            that you have not set timeouts too aggressively.
-            You will see preemption log messages in your JobTracker's output
-            log (HADOOP_LOG_DIR/hadoop-jobtracker-*.log).
-            The messages look as follows:

-            Should preempt 2 tasks for job_20090101337_0001: tasksDueToMinShare = 2, tasksDueToFairShare = 0
-          

-            mapred.fairscheduler.update.interval
-          
-            Interval at which to update fair share calculations. The default
-            of 500ms works well for clusters with fewer than 500 nodes, 
-            but larger values reduce load on the JobTracker for larger clusters.
-            Integer value in milliseconds, default: 500.
-          

-            mapred.fairscheduler.preemption.interval
-          
-            Interval at which to check for tasks to preempt. The default
-            of 15s works well for timeouts on the order of minutes.
-            It is not recommended to set timeouts much smaller than this
-            amount, but you can use this value to make preemption computations
-            run more often if you do set such timeouts. A value of less than
-            5s will probably be too small, however, as it becomes less than
-            the inter-heartbeat interval.
-            Integer value in milliseconds, default: 15000.
-          

-            mapred.fairscheduler.weightadjuster
-          
-          An extension point that lets you specify a class to adjust the 
-          weights of running jobs. This class should implement the 
-          WeightAdjuster interface. There is currently one example 
-          implementation - NewJobWeightBooster, which increases the 
-          weight of jobs for the first 5 minutes of their lifetime to let 
-          short jobs finish faster. To use it, set the weightadjuster 
-          property to the full class name, 
-          org.apache.hadoop.mapred.NewJobWeightBooster.
-          NewJobWeightBooster itself provides two parameters for setting the 
-          duration and boost factor.
-          
    
-          
  • mapred.newjobweightbooster.factor
-            Factor by which new jobs weight should be boosted. 
-            Default is 3.
    • 
-          
  • mapred.newjobweightbooster.duration
-            Boost duration in milliseconds. Default is 300000 for 5 minutes.
    • 
-          

-          

-            mapred.fairscheduler.loadmanager
-          
-            An extension point that lets you specify a class that determines 
-            how many maps and reduces can run on a given TaskTracker. This class 
-            should implement the LoadManager interface. By default the task caps 
-            in the Hadoop config file are used, but this option could be used to 
-            make the load based on available memory and CPU utilization for example.
-          

-            mapred.fairscheduler.taskselector
-          
-          An extension point that lets you specify a class that determines 
-          which task from within a job to launch on a given tracker. This can be 
-          used to change either the locality policy (e.g. keep some jobs within 
-          a particular rack) or the speculative execution algorithm (select 
-          when to launch speculative tasks). The default implementation uses 
-          Hadoop's default algorithms from JobInProgress.
-          

-      
  
-      

-        Allocation File (fair-scheduler.xml)
-        

-        The allocation file configures minimum shares, running job
-        limits, weights and preemption timeouts for each pool.
-        Only users/pools whose values differ from the defaults need to be
-        explicitly configured in this file.
-        The allocation file is located in
-        HADOOP_PREFIX/conf/fair-scheduler.xml.
-        It can contain the following types of elements:
-        

-        
    
-        
  • pool elements, which configure each pool.
-        These may contain the following sub-elements:
-          
      
-          
    • minMaps and minReduces,
-            to set the pool's minimum share of task slots.
      • 
-          
    • maxMaps and maxReduces, to set the
-            pool's maximum concurrent task slots.
      • 
-          
    • schedulingMode, the pool's internal scheduling mode,
-          which can be fair for fair sharing or fifo for
-          first-in-first-out.
      • 
-          
    • maxRunningJobs, 
-          to limit the number of jobs from the 
-          pool to run at once (defaults to infinite).
      • 
-          
    • weight, to share the cluster 
-          non-proportionally with other pools. For example, a pool with weight 2.0 will get a 2x higher share than other pools. The default weight is 1.0.
      • 
-          
    • minSharePreemptionTimeout, the
-            number of seconds the pool will wait before
-            killing other pools' tasks if it is below its minimum share
-            (defaults to infinite).
      • 
-          
    
-        
    • 
-        
  • user elements, which may contain a 
-        maxRunningJobs element to limit 
-        jobs. Note that by default, there is a pool for each 
-        user, so per-user limits are not necessary.
    • 
-        
  • poolMaxJobsDefault, which sets the default running 
-        job limit for any pools whose limit is not specified.
    • 
-        
  • userMaxJobsDefault, which sets the default running 
-        job limit for any users whose limit is not specified.
    • 
-        
  • defaultMinSharePreemptionTimeout, 
-        which sets the default minimum share preemption timeout 
-        for any pools where it is not specified.
    • 
-        
  • fairSharePreemptionTimeout, 
-        which sets the preemption timeout used when jobs are below half
-        their fair share.
    • 
-        
  • defaultPoolSchedulingMode, which sets the default scheduling 
-        mode (fair or fifo) for pools whose mode is
-        not specified.
    • 
-        

-        

-        Pool and user elements only required if you are setting
-        non-default values for the pool/user. That is, you do not need to
-        declare all users and all pools in your config file before running
-        the fair scheduler. If a user or pool is not listed in the config file,
-        the default values for limits, preemption timeouts, etc will be used.
-        

-        

-        An example allocation file is given below : 

-
-<?xml version="1.0"?>  
-<allocations>  
-  <pool name="sample_pool">
-    <minMaps>5</minMaps>
-    <minReduces>5</minReduces>
-    <maxMaps>25</maxMaps>
-    <maxReduces>25</maxReduces>
-    <minSharePreemptionTimeout>300</minSharePreemptionTimeout>
-  </pool>
-  <mapreduce.job.user.name="sample_user">
-    <maxRunningJobs>6</maxRunningJobs>
-  </user>
-  <userMaxJobsDefault>3</userMaxJobsDefault>
-  <fairSharePreemptionTimeout>600</fairSharePreemptionTimeout>
-</allocations>
-
-        

-        This example creates a pool sample_pool with a guarantee of 5 map 
-        slots and 5 reduce slots. The pool also has a minimum share preemption
-        timeout of 300 seconds (5 minutes), meaning that if it does not get its
-        guaranteed share within this time, it is allowed to kill tasks from
-        other pools to achieve its share. The pool has a cap of 25 map and 25
-        reduce slots, which means that once 25 tasks are running, no more will
-        be scheduled even if the pool's fair share is higher.
-        The example also limits the number of running jobs 
-        per user to 3, except for sample_user, who can run 6 jobs concurrently. 
-        Finally, the example sets a fair share preemption timeout of 600 seconds
-        (10 minutes). If a job is below half its fair share for 10 minutes, it
-        will be allowed to kill tasks from other jobs to achieve its share.
-        Note that the preemption settings require preemption to be
-        enabled in mapred-site.xml as described earlier.
-        

-        

-        Any pool not defined in the allocation file will have no guaranteed 
-        capacity and no preemption timeout. Also, any pool or user with no max 
-        running jobs set in the file will be allowed to run an unlimited 
-        number of jobs.
-        

-      

-      

-        Access Control Lists (ACLs)
-        

-          The fair scheduler can be used in tandem with the "queue" based access
-          control system in MapReduce to restrict which pools each user can access.
-          To do this, first enable ACLs and set up some queues as described in the
-          MapReduce usage guide,
-          then set the fair scheduler to use one pool per queue by adding
-          the following property in HADOOP_CONF_DIR/mapred-site.xml:
-        

-
-<property>
-  <name>mapred.fairscheduler.poolnameproperty</name>
-  <value>mapreduce.job.queuename</value>
-</property>
-
-        

-          You can then set the minimum share, weight, and internal scheduling mode
-          for each pool as described earlier.
-          In addition, make sure that users submit jobs to the right queue by setting
-          the mapreduce.job.queuename property in their jobs.
-        

-      

-    

-    

-     Administration
-    

-      The fair scheduler provides support for administration at runtime 
-      through two mechanisms:
-    
 
-    
    
-    
  1. 
-      It is possible to modify minimum shares, limits, weights, preemption
-      timeouts and pool scheduling modes at runtime by editing the allocation
-      file. The scheduler will reload this file 10-15 seconds after it 
-      sees that it was modified.
-     
    2. 
-     
  2. 
-     Current jobs, pools, and fair shares  can be examined through the 
-     JobTracker's web interface, at
-     http://<JobTracker URL>/scheduler. 
-     On this interface, it is also possible to modify jobs' priorities or 
-     move jobs from one pool to another and see the effects on the fair 
-     shares (this requires JavaScript).
-     
    3. 
-    

-    

-      The following fields can be seen for each job on the web interface:
-     

-     
    
-     
  • Submitted - Date and time job was submitted.
    • 
-     
  • JobID, User, Name - Job identifiers as on the standard 
-     web UI.
    • 
-     
  • Pool - Current pool of job. Select another value to move job to 
-     another pool.
    • 
-     
  • Priority - Current priority. Select another value to change the 
-     job's priority
    • 
-     
  • Maps/Reduces Finished: Number of tasks finished / total tasks.
    • 
-     
  • Maps/Reduces Running: Tasks currently running.
    • 
-     
  • Map/Reduce Fair Share: The average number of task slots that this 
-     job should have at any given time according to fair sharing. The actual
-     number of tasks will go up and down depending on how much compute time
-     the job has had, but on average it will get its fair share amount.
    • 
-     

-     

-     In addition, it is possible to view an "advanced" version of the web 
-     UI by going to http://<JobTracker URL>/scheduler?advanced. 
-     This view shows two more columns:
-     

-     
    
-     
  • Maps/Reduce Weight: Weight of the job in the fair sharing 
-     calculations. This depends on priority and potentially also on 
-     job size and job age if the sizebasedweight and 
-     NewJobWeightBooster are enabled.
    • 
-     

-    

-    

-      Metrics
-      

-        The fair scheduler can export metrics using the Hadoop metrics interface.
-        This can be enabled by adding an entry to hadoop-metrics.properties
-        to enable the fairscheduler metrics context. For example, to
-        simply retain the metrics in memory so they may be viewed in the /metrics
-        servlet:
-      

-      

-        fairscheduler.class=org.apache.hadoop.metrics.spi.NoEmitMetricsContext
-      

-      

-        Metrics are generated for each pool and job, and contain the same information that
-        is visible on the /scheduler web page.
-      

-

-           mapreduce.{map|reduce}.ulimit: The slaves where
-           tasks are run could be configured with a ulimit value that
-           applies a limit to every process that is launched on the slave.
-           If the task, or any child that the task launches (like in
-           streaming), requires more than the configured limit, this option
-           must be used. The value is given in kilobytes. For example, to
-           increase the ulimit to 1G, the option should be set to 1048576.
-           Note that this value is a per process limit. Since it applies 
-           to the JVM as well, the heap space given to the JVM through 
-           the mapreduce.{map|reduce}.java.opts should be less
-           than the value configured for the ulimit. Otherwise the JVM
-           will not start.

-           mapreduce.{map|reduce}.memory.mb: In some 
-           environments, administrators might have configured a total limit
-           on the virtual memory used by the entire process tree for a task, 
-           including all processes launched recursively by the task or 
-           its children, like in streaming. More details about this can be
-           found in the section on 
-           
-           Monitoring Task Memory Usage in the Cluster SetUp guide.
-           If a task requires more virtual memory for its entire tree, 
-           this option 
-           must be used. The value is given in MB. For example, to set 
+           mapreduce.{map|reduce}.memory.mb:
+           This parameter configures how many megabytes of physical memory
+           the job requires for its map and reduce tasks. It must be configured
+           to be slightly larger than the configured Java heap size above,
+           to account for the fact that the JVM uses physical memory beyond
+           just the heap. An overhead of 20% to 30% is usually sufficient.
+           
    
+           Note that, the smaller the amount of memory specified for tasks
+           in this configuration, the larger the number of tasks that
+           can be run in parallel.
    
+
+           The value is given in MB. For example, to set 
            the limit to 1G, the option should be set to 1024. Note that this 
            value does not automatically influence the per process ulimit or 
            heap space. Hence, you may need to set those parameters as well 
            (as described above) in order to give your tasks the right amount 
            of memory.
+           
    
+           If the amount of physical memory used by your task exceeds the
+           configured value, the NodeManager will automatically kill the task.

-           mapreduce.{map|reduce}.memory.physical.mb: 
-           This parameter is similar to

-           how much physical memory is required by a task for its entire
-           tree of processes. The parameter is applicable if administrators
-           have configured a total limit on the physical memory used by
-           all MapReduce tasks.

+  Apache Hadoop ${project.version}

+  
+Apache Hadoop 0.23
+
+  Apache Hadoop 0.23 consists of significant improvements over the previous 
+  stable release (hadoop-0.20.205).
+
+  Here is a short overview of the improvments to both HDFS and MapReduce.
+
+  * {HDFS Federation}
+
+  In order to scale the name service horizontally, federation uses multiple 
+  independent Namenodes/Namespaces. The Namenodes are federated, that is, the 
+  Namenodes are independent and don't require coordination with each other. 
+  The datanodes are used as common storage for blocks by all the Namenodes. 
+  Each datanode registers with all the Namenodes in the cluster. Datanodes 
+  send periodic heartbeats and block reports and handles commands from the 
+  Namenodes.
+
+  More details are available in the 
+  {{{./hadoop-yarn/hadoop-yarn-site/Federation.html}HDFS Federation}}
+  document.
+
+  * {MapReduce NextGen aka YARN aka MRv2}
+
+  The new architecture introduced in hadoop-0.23, divides the two major 
+  functions of the JobTracker: resource management and job life-cycle management 
+  into separate components.
+
+  The new ResourceManager manages the global assignment of compute resources to 
+  applications and the per-application ApplicationMaster manages the 
+  application’s scheduling and coordination. 
+
+  An application is either a single job in the sense of classic MapReduce jobs 
+  or a DAG of such jobs. 
+
+  The ResourceManager and per-machine NodeManager daemon, which manages the 
+  user processes on that machine, form the computation fabric. 
+
+  The per-application ApplicationMaster is, in effect, a framework specific 
+  library and is tasked with negotiating resources from the ResourceManager and 
+  working with the NodeManager(s) to execute and monitor the tasks.
+
+  More details are available in the 
+  {{{./hadoop-yarn/hadoop-yarn-site/YARN.html}YARN}}
+  document.
+
+Getting Started
+
+  The Hadoop documentation includes the information you need to get started using
+  Hadoop. Begin with the
+  {{{./hadoop-yarn/hadoop-yarn-site/SingleCluster.html}Single Node Setup}} which
+  shows you how to set up a single-node Hadoop installation. Then move on to the
+  {{{./hadoop-yarn/hadoop-yarn-site/ClusterSetup.html}Cluster Setup}} to learn how
+  to set up a multi-node Hadoop installation.
