|
|
|
|
HADOOP-1230. Add new map/reduce API and deprecate the old one. Generally,
|
|
the old code should work without problem. The new api is in
|
|
org.apache.hadoop.mapreduce and the old classes in org.apache.hadoop.mapred
|
|
are deprecated. Differences in the new API:
|
|
1. All of the methods take Context objects that allow us to add new
|
|
methods without breaking compatability.
|
|
2. Mapper and Reducer now have a "run" method that is called once and
|
|
contains the control loop for the task, which lets applications
|
|
replace it.
|
|
3. Mapper and Reducer by default are Identity Mapper and Reducer.
|
|
4. The FileOutputFormats use part-r-00000 for the output of reduce 0 and
|
|
part-m-00000 for the output of map 0.
|
|
5. The reduce grouping comparator now uses the raw compare instead of
|
|
object compare.
|
|
6. The number of maps in FileInputFormat is controlled by min and max
|
|
split size rather than min size and the desired number of maps.
|

|
|
|
|
HADOOP-3136. Fixed the default scheduler to assign multiple tasks to each
|
|
tasktracker per heartbeat, when feasible. To ensure locality isn't hurt
|
|
too badly, the scheudler will not assign more than one off-switch task per
|
|
heartbeat. The heartbeat interval is also halved since the task-tracker is
|
|
fixed to no longer send out heartbeats on each task completion. A
|
|
slow-start for scheduling reduces is introduced to ensure that reduces
|
|
aren't started till sufficient number of maps are done, else reduces of
|
|
jobs whose maps aren't scheduled might swamp the cluster.

|
|
DFS Used%: DFS used space/Present Capacity
|
|
(Suresh Srinivas via hairong)

|
HADOOP-4430. Further change the cluster summary at name node web that was
|
|
changed in HADOOP-2816:
|
|
Non DFS Used - This indicates the disk space taken by non DFS file from
|
|
the Configured capacity
|
|
DFS Used % - DFS Used % of Configured Capacity
|
|
DFS Remaining % - Remaing % Configured Capacity available for DFS use
|

INCOMPATIBLE CHANGES
|
|
|
|
HADOOP-2703. The default options to fsck skips checking files
|
|
that are being written to. The output of fsck is incompatible
|
|
with previous release. (lohit vijayarenu via dhruba)
|
|
|
|
HADOOP-2865. FsShell.ls() printout format changed to print file names
|
|
in the end of the line. (Edward J. Yoon via shv)
|
|
|
|
HADOOP-3283. The Datanode has a RPC server. It currently supports
|
|
two RPCs: the first RPC retrives the metadata about a block and the
|
|
second RPC sets the generation stamp of an existing block.
|
|
(Tsz Wo (Nicholas), SZE via dhruba)
|
|
|
|
HADOOP-2797. Code related to upgrading to 0.14 (Block CRCs) is
|
|
removed. As result, upgrade to 0.18 or later from 0.13 or earlier
|
|
is not supported. If upgrading from 0.13 or earlier is required,
|
|
please upgrade to an intermediate version (0.14-0.17) and then
|
|
to this version. (rangadi)
|
|
|
|
HADOOP-544. This issue introduces new classes JobID, TaskID and
|
|
TaskAttemptID, which should be used instead of their string counterparts.
|
|
Functions in JobClient, TaskReport, RunningJob, jobcontrol.Job and
|
|
TaskCompletionEvent that use string arguments are deprecated in favor
|
|
of the corresponding ones that use ID objects. Applications can use
|
|
xxxID.toString() and xxxID.forName() methods to convert/restore objects
|
|
to/from strings. (Enis Soztutar via ddas)
|
|
|
|
HADOOP-2188. RPC client sends a ping rather than throw timeouts.
|
|
RPC server does not throw away old RPCs. If clients and the server are on
|
|
different versions, they are not able to function well. In addition,
|
|
The property ipc.client.timeout is removed from the default hadoop
|
|
configuration. It also removes metrics RpcOpsDiscardedOPsNum. (hairong)
|
|
|
|
HADOOP-2181. This issue adds logging for input splits in Jobtracker log
|
|
and jobHistory log. Also adds web UI for viewing input splits in job UI
|
|
and history UI. (Amareshwari Sriramadasu via ddas)

|
|
|
HADOOP-3226. Run combiners multiple times over map outputs as they
|
|
are merged in both the map and the reduce tasks. (cdouglas via omalley)
|
|
|
|
HADOOP-3329. DatanodeDescriptor objects should not be stored in the
|
|
fsimage. (dhruba)
|
|
|
|
HADOOP-2656. The Block object has a generation stamp inside it.
|
|
Existing blocks get a generation stamp of 0. This is needed to support
|
|
appends. (dhruba)
|
|
|
|
HADOOP-3390. Removed deprecated ClientProtocol.abandonFileInProgress().
|
|
(Tsz Wo (Nicholas), SZE via rangadi)
|
|
|
|
HADOOP-3405. Made some map/reduce internal classes non-public:

|
|
CompletedJobStatusStore. (enis via omaley)
|
|
|
|
HADOOP-3265. Removed depcrecated API getFileCacheHints().
|
|
(Lohit Vijayarenu via rangadi)
|
|
|
|
HADOOP-3310. The namenode instructs the primary datanode to do lease
|
|
recovery. The block gets a new generation stamp.
|
|
(Tsz Wo (Nicholas), SZE via dhruba)
|
|
|
|
HADOOP-2909. Improve IPC idle connection management. Property
|
|
ipc.client.maxidletime is removed from the default configuration,
|
|
instead it is defined as twice of the ipc.client.connection.maxidletime.
|
|
A connection with outstanding requests won't be treated as idle.
|
|
(hairong)
|
|
|
|
HADOOP-3459. Change in the output format of dfs -ls to more closely match
|
|
/bin/ls. New format is: perm repl owner group size date name
|
|
(Mukund Madhugiri via omally)
|
|
|
|
HADOOP-3113. An fsync invoked on a HDFS file really really
|
|
persists data! The datanode moves blocks in the tmp directory to
|
|
the real block directory on a datanode-restart. (dhruba)
|
|
|
|
HADOOP-3452. Change fsck to return non-zero status for a corrupt
|
|
FileSystem. (lohit vijayarenu via cdouglas)
|
|
|
|
HADOOP-3193. Include the address of the client that found the corrupted
|
|
block in the log. Also include a CorruptedBlocks metric to track the size
|
|
of the corrupted block map. (cdouglas)
|
|
|
|
HADOOP-3512. Separate out the tools into a tools jar. (omalley)
|
|
|
|
HADOOP-3598. Ensure that temporary task-output directories are not created
|
|
if they are not necessary e.g. for Maps with no side-effect files.
|
|
(acmurthy)
|
|
|
|
HADOOP-3665. Modify WritableComparator so that it only creates instances
|
|
of the keytype if the type does not define a WritableComparator. Calling
|
|
the superclass compare will throw a NullPointerException. Also define
|
|
a RawComparator for NullWritable and permit it to be written as a key
|
|
to SequenceFiles. (cdouglas)
|
|
|
|
HADOOP-3673. Avoid deadlock caused by DataNode RPC receoverBlock().
|
|
(Tsz Wo (Nicholas), SZE via rangadi)

(Lohit Vjayarenu via rangadi)
|
|
|
|
HADOOP-3221. Adds org.apache.hadoop.mapred.lib.NLineInputFormat, which

INCOMPATIBLE CHANGES
|
|
|
|
HADOOP-1245. Use the mapred.tasktracker.tasks.maximum value
|
|
configured on each tasktracker when allocating tasks, instead of
|
|
the value configured on the jobtracker. InterTrackerProtocol
|
|
version changed from 5 to 6. (Michael Bieniosek via omalley)
|
|
|
|
HADOOP-1843. Removed code from Configuration and JobConf deprecated by
|
|
HADOOP-785 and a minor fix to Configuration.toString. Specifically the
|
|
important change is that mapred-default.xml is no longer supported and
|
|
Configuration no longer supports the notion of default/final resources.
|
|
(acmurthy)
|
|
|
|
HADOOP-1302. Remove deprecated abacus code from the contrib directory.
|
|
This also fixes a configuration bug in AggregateWordCount, so that the
|
|
job now works. (enis)

|
|
HADOOP-2288. Enhance FileSystem API to support access control.
|
|
(Tsz Wo (Nicholas), SZE via dhruba)

port is zero. Otherwise it uses the specified port. Also combines
|
|
the configuration attributes for the servers' bind address and
|
|
port from "x.x.x.x" and "y" to "x.x.x.x:y".
|
|
Deprecated configuration variables:
|
|
dfs.info.bindAddress
|
|
dfs.info.port
|
|
dfs.datanode.bindAddress
|
|
dfs.datanode.port
|

|
|
(Sanjay Radia via dhruba)
|
|
|
|
HADOOP-2567. Add FileSystem#getHomeDirectory(), which returns the
|
|
user's home directory in a FileSystem as a fully-qualified path.
|
|
FileSystem#getWorkingDirectory() is also changed to return a
|
|
fully-qualified path, which can break applications that attempt
|
|
to, e.g., pass LocalFileSystem#getWorkingDir().toString() directly
|
|
to java.io methods that accept file names. (cutting)
|
|
|
|
HADOOP-2514. Change trash feature to maintain a per-user trash

|
writes to a HDFS file. Changed Data Transfer Version from 7 to 8.
|
|
(dhruba)

incompatible change since distcp may not be able to copy files
|
|
from cluster A (compiled with this patch) to cluster B (compiled
|
|
with previous versions). (Tsz Wo (Nicholas), SZE via dhruba)
|
|

|
|
|
|
IMPROVEMENTS
|
|
|
|

|
|
* cluster_setup.html helps admins to configure and setup non-trivial
|
|
hadoop clusters.
|
|
* mapred_tutorial.html is a comprehensive Map-Reduce tutorial.

|
|
(acmurthy via omalley)
|
|
|
|
HADOOP-1874. Move task-outputs' promotion/discard to a separate thread
|
|
distinct from the main heartbeat-processing thread. The main upside being

|
that we do not lock-up the JobTracker during HDFS operations, which

otherwise may lead to lost tasktrackers if the NameNode is unresponsive.
|
|
(Devaraj Das via acmurthy)
|
|
|
|
HADOOP-2026. Namenode prints out one log line for "Number of transactions"

at most once every minute. (Dhruba Borthakur)
|
|
|
|
HADOOP-2022. Ensure that status information for successful tasks is correctly

|
|
(Amar Kamat via acmurthy)
|
|
|
|
HADOOP-2031. Correctly maintain the taskid which takes the TIP to
|
|
completion, failing which the case of lost tasktrackers isn't handled

|
is never rescheduled elsewhere, leading to hung reduces.
|
|
(Devaraj Das via acmurthy)

|
|
HADOOP-2023. Disable TestLocalDirAllocator on Windows.
|
|
(Hairong Kuang via nigel)
|
|
|
|
HADOOP-2016. Ignore status-updates from FAILED/KILLED tasks at the
|
|
TaskTracker. This fixes a race-condition which caused the tasks to wrongly
|
|
remain in the RUNNING state even after being killed by the JobTracker and
|
|
thus handicap the cleanup of the task's output sub-directory. (acmurthy)
|
|
|
|
HADOOP-1771. Fix a NullPointerException in streaming caused by an

|
sortedLease lock. (Dhruba Borthakur)
|
|
|
|
HADOOP-2051. The TaskCommit thread should not die for exceptions other

|
than the InterruptedException. This behavior is there for the other long
|
|
running threads in the JobTracker. (Arun C Murthy via ddas)
|
|
|
|
HADOOP-1973. The FileSystem object would be accessed on the JobTracker
|
|
through a RPC in the InterTrackerProtocol. The check for the object being
|
|
null was missing and hence NPE would be thrown sometimes. This issue fixes
|
|
that problem. (Amareshwari Sri Ramadasu via ddas)
|
|
|
|
HADOOP-2033. The SequenceFile.Writer.sync method was a no-op, which caused
|

very uneven splits for applications like distcp that count on them.
|
|
(omalley)
|
|
|
|
HADOOP-2070. Added a flush method to pipes' DownwardProtocol and call

|
|
12. HADOOP-880. Fix S3 FileSystem to remove directories.
|

|
MapFileOutputFormat. (cutting)
|
|
|

|
|
|
|
15. HADOOP-726. Deprecate FileSystem locking methods. They are not

5. HADOOP-629. Fix RPC services to better check the protocol name and
|
|
version. (omalley via cutting)
|
|
|
|
6. HADOOP-774. Limit the number of invalid blocks returned with
|
|
heartbeats by the namenode to datanodes. Transmitting and
|
|
processing very large invalid block lists can tie up both the
|
|
namenode and datanode for too long. (Dhruba Borthakur via cutting)
|
|
|
|
7. HADOOP-738. Change 'dfs -get' command to not create CRC files by
|
|
default, adding a -crc option to force their creation.
|
|
(Milind Bhandarkar via cutting)
|
|
|
|
8. HADOOP-676. Improved exceptions and error messages for common job
|
|
input specification errors. (Sanjay Dahiya via cutting)

|
|
jobs that were running when it was last stopped.
|
|
(Sanjay Dahiya via cutting)
|
|
|
|
12. HADOOP-331. Write all map outputs to a single file with an index,
|
|
rather than to a separate file per reduce task. This should both
|
|
speed the shuffle and make things more scalable.
|
|
(Devaraj Das via cutting)
|
|
|
|
13. HADOOP-818. Fix contrib unit tests to not depend on core unit
|
|
tests. (omalley via cutting)
|

|
|
(Dhruba Borthakur via cutting)
|
|
|
|
22. HADOOP-673. Give each task its own working directory again.
|
|
(Mahadev Konar via cutting)
|
|
|
|
23. HADOOP-571. Extend the syntax of Path to be a URI; to be
|
|
optionally qualified with a scheme and authority. The scheme
|
|
determines the FileSystem implementation, while the authority
|
|
determines the FileSystem instance. New FileSystem
|
|
implementations may be provided by defining an fs.<scheme>.impl
|
|
property, naming the FileSystem implementation class. This
|
|
permits easy integration of new FileSystem implementations.
|
|
(cutting)
|
|
|
|
24. HADOOP-720. Add an HDFS white paper to website.
|
|
(Dhruba Borthakur via cutting)

|
|
zero map tasks. (omalley via cutting)
|
|
|
|
26. HADOOP-454. Add a 'dfs -dus' command that provides summary disk
|
|
usage. (Hairong Kuang via cutting)
|
|
|
|
27. HADOOP-574. Add an Amazon S3 implementation of FileSystem. To
|
|
use this, one need only specify paths of the form
|
|
s3://id:secret@bucket/. Alternately, the AWS access key id and
|
|
secret can be specified in your config, with the properties
|
|
fs.s3.awsAccessKeyId and fs.s3.awsSecretAccessKey.
|
|
(Tom White via cutting)
|
|
|
|
28. HADOOP-824. Rename DFSShell to be FsShell, since it applies
|
|
generically to all FileSystem implementations. (cutting)
|
|
|
|
29. HADOOP-813. Fix map output sorting to report progress, so that
|
|
sorts which take longer than the task timeout do not fail.

|
|
(Alejandro Abdelnur via cutting)
|
|
|
|
33. HADOOP-829. Within HDFS, clearly separate three different
|
|
representations for datanodes: one for RPCs, one for
|
|
namenode-internal use, and one for namespace persistence.
|
|
(Dhruba Borthakur via cutting)
|
|
|
|
34. HADOOP-823. Fix problem starting datanode when not all configured
|
|
data directories exist. (Bryan Pendleton via cutting)
|
|
|
|
35. HADOOP-451. Add a Split interface. CAUTION: This incompatibly
|
|
changes the InputFormat and RecordReader interfaces. Not only is
|
|
FileSplit replaced with Split, but a FileSystem parameter is no
|
|
longer passed in several methods, input validation has changed,
|
|
etc. (omalley via cutting)
|
|
|
|
36. HADOOP-814. Optimize locking in namenode. (Dhruba Borthakur via cutting)
|
|
|
|
37. HADOOP-738. Change 'fs -put' and 'fs -get' commands to accept
|
|
standard input and output, respectively. Standard i/o is
|
|
specified by a file named '-'. (Wendy Chien via cutting)
|
|
|

38. HADOOP-835. Fix a NullPointerException reading record-compressed
|
|
SequenceFiles. (Hairong Kuang via cutting)
|
|
|
|
39. HADOOP-836. Fix a MapReduce bug on Windows, where the wrong
|
|
FileSystem was used. Also add a static FileSystem.getLocal()
|
|
method and better Path checking in HDFS, to help avoid such issues
|
|
in the future. (omalley via cutting)
|
|
|
|
40. HADOOP-837. Improve RunJar utility to unpack jar file
|
|
hadoop.tmp.dir, rather than the system temporary directory.
|
|
(Hairong Kuang via cutting)
|
|
|
|
41. HADOOP-841. Fix native library to build 32-bit version even when
|
|
on a 64-bit host, if a 32-bit JVM is used. (Arun C Murthy via cutting)
|
|
|
|
42. HADOOP-838. Fix tasktracker to pass java.library.path to
|
|
sub-processes, so that libhadoop.a is found.
|
|
(Arun C Murthy via cutting)
|
|
|
|
43. HADOOP-844. Send metrics messages on a fixed-delay schedule
|
|
instead of a fixed-rate schedule. (David Bowen via cutting)

|
|
(Sanjay Dahiya via cutting)

|
|
in releases. (cutting)
|
|

|
|
distributions. Also add contrib and example documentation to
|
|
distributed javadoc, in separate sections. (Nigel Daley via cutting)
|
|
|
|
52. HADOOP-846. Report progress during entire map, as sorting of
|
|
intermediate outputs may happen at any time, potentially causing
|
|
task timeouts. (Devaraj Das via cutting)
|
|
|
|
53. HADOOP-840. In task tracker, queue task cleanups and perform them
|
|
in a separate thread. (omalley & Mahadev Konar via cutting)
|
|
|
|
54. HADOOP-681. Add to HDFS the ability to decommission nodes. This
|
|
causes their blocks to be re-replicated on other nodes, so that
|
|
they may be removed from a cluster. (Dhruba Borthakur via cutting)
|
|
|
|
55. HADOOP-470. In HDFS web ui, list the datanodes containing each
|
|
copy of a block. (Hairong Kuang via cutting)
|
|
|
|
56. HADOOP-700. Change bin/hadoop to only include core jar file on
|
|
classpath, not example, test, etc. Also rename core jar to
|
|
hadoop-${version}-core.jar so that it can be more easily
|
|
identified. (Nigel Daley via cutting)
|
|
|
|
57. HADOOP-619. Extend InputFormatBase to accept individual files and
|
|
glob patterns as MapReduce inputs, not just directories. Also
|

|
|
not completely cleaned up. (Mahadev Konar via cutting)
|
|
|
|

|
|
sort pass over the data and should consequently significantly
|
|
decrease overall processing time. (Devaraj Das via cutting)
|
|
|
|
19. HADOOP-661. Make each job's configuration visible through the web
|
|
ui. (Arun C Murthy via cutting)
|
|
|
|
20. HADOOP-489. In MapReduce, separate user logs from system logs.
|
|
Each task's log output is now available through the web ui. (Arun
|
|
C Murthy via cutting)
|
|
|

22. HADOOP-668. Improvements to the web-based DFS browser.
|
|
(Hairong Kuang via cutting)
|
|
|
|
23. HADOOP-715. Fix build.xml so that test logs are written in build

|
directory, rather than in CWD. (Arun C Murthy via cutting)
|
|
|
|
24. HADOOP-538. Add support for building an optional native library,
|
|
libhadoop.so, that improves the performance of zlib-based

|
to be smaller than the buffer size, typically only when debugging.
|
|
(Milind Bhandarkar via cutting)
|
|
|
|
26. HADOOP-695. Fix a NullPointerException in contrib/streaming.
|
|
(Hairong Kuang via cutting)
|
|
|
|
27. HADOOP-652. In DFS, when a file is deleted, the block count is
|
|
now decremented. (Vladimir Krokhmalyov via cutting)
|
|
|
|
28. HADOOP-725. In DFS, optimize block placement algorithm,
|
|
previously a performance bottleneck. (Milind Bhandarkar via cutting)
|
|
|
|
29. HADOOP-723. In MapReduce, fix a race condition during the
|
|
shuffle, which resulted in FileNotFoundExceptions. (omalley via cutting)

|
|
contain control characters. (Dhruba Borthakur via cutting)
|
|
|
|
33. HADOOP-677. In IPC, permit a version header to be transmitted
|
|
when connections are established. This will permit us to change
|
|
the format of IPC requests back-compatibly in subsequent releases.
|
|
(omalley via cutting)
|
|
|
|
34. HADOOP-699. Fix DFS web interface so that filesystem browsing

|
works correctly, using the right port number. Also add support
|
|
for sorting datanode list by various columns.
|
|
(Raghu Angadi via cutting)
|
|
|
|
35. HADOOP-76. Implement speculative reduce. Now when a job is
|
|
configured for speculative execution, both maps and reduces will
|
|
execute speculatively. Reduce outputs are written to temporary
|
|
location and moved to the final location when reduce is complete.
|
|
(Sanjay Dahiya via cutting)
|
|
|
|
36. HADOOP-736. Roll back to Jetty 5.1.4, due to performance problems

|
|
|
|
1. HADOOP-477. Extend contrib/streaming to scan the PATH environment
|
|
variables when resolving executable program names.
|
|
(Dhruba Borthakur via cutting)
|
|
|
|
2. HADOOP-583. In DFSClient, reduce the log level of re-connect
|
|
attempts from 'info' to 'debug', so they are not normally shown.
|
|
(Konstantin Shvachko via cutting)
|
|
|
|
3. HADOOP-498. Re-implement DFS integrity checker to run server-side,
|
|
for much improved performance. (Milind Bhandarkar via cutting)
|
|
|
|
4. HADOOP-586. Use the jar name for otherwise un-named jobs.
|
|
(Sanjay Dahiya via cutting)
|
|
|
|
5. HADOOP-514. Make DFS heartbeat interval configurable.
|
|
(Milind Bhandarkar via cutting)
|
|
|
|
6. HADOOP-588. Fix logging and accounting of failed tasks.
|
|
(Sanjay Dahiya via cutting)
|
|
|
|
7. HADOOP-462. Improve command line parsing in DFSShell, so that
|
|
incorrect numbers of arguments result in informative errors rather
|
|
than ArrayOutOfBoundsException. (Dhruba Borthakur via cutting)
|
|
|
|
8. HADOOP-561. Fix DFS so that one replica of each block is written
|
|
locally, if possible. This was the intent, but there as a bug.
|
|
(Dhruba Borthakur via cutting)
|
|
|
|
9. HADOOP-610. Fix TaskTracker to survive more exceptions, keeping
|
|
tasks from becoming lost. (omalley via cutting)
|
|
|
|
10. HADOOP-625. Add a servlet to all http daemons that displays a
|
|
stack dump, useful for debugging. (omalley via cutting)
|
|
|
|
11. HADOOP-554. Fix DFSShell to return -1 for errors.
|
|
(Dhruba Borthakur via cutting)
|
|
|
|
12. HADOOP-626. Correct the documentation in the NNBench example
|
|
code, and also remove a mistaken call there.
|
|
(Nigel Daley via cutting)
|
|
|
|
13. HADOOP-634. Add missing license to many files.
|
|
(Nigel Daley via cutting)
|
|
|
|
14. HADOOP-627. Fix some synchronization problems in MiniMRCluster
|
|
that sometimes caused unit tests to fail. (Nigel Daley via cutting)
|
|
|
|
15. HADOOP-563. Improve the NameNode's lease policy so that leases
|
|
are held for one hour without renewal (instead of one minute).
|
|
However another attempt to create the same file will still succeed
|
|
if the lease has not been renewed within a minute. This prevents
|
|
communication or scheduling problems from causing a write to fail
|
|
for up to an hour, barring some other process trying to create the
|
|
same file. (Dhruba Borthakur via cutting)
|
|
|
|
16. HADOOP-635. In DFSShell, permit specification of multiple files
|
|
as the source for file copy and move commands.
|
|
(Dhruba Borthakur via cutting)
|
|
|
|
17. HADOOP-641. Change NameNode to request a fresh block report from
|
|
a re-discovered DataNode, so that no-longer-needed replications
|
|
are stopped promptly. (Konstantin Shvachko via cutting)
|
|
|
|
18. HADOOP-642. Change IPC client to specify an explicit connect
|
|
timeout. (Konstantin Shvachko via cutting)
|
|
|
|
19. HADOOP-638. Fix an unsynchronized access to TaskTracker's
|
|
internal state. (Nigel Daley via cutting)
|
|
|
|
20. HADOOP-624. Fix servlet path to stop a Jetty warning on startup.
|
|
(omalley via cutting)
|
|
|
|
21. HADOOP-578. Failed tasks are no longer placed at the end of the
|
|
task queue. This was originally done to work around other
|
|
problems that have now been fixed. Re-executing failed tasks
|
|
sooner causes buggy jobs to fail faster. (Sanjay Dahiya via cutting)
|
|
|
|
22. HADOOP-658. Update source file headers per Apache policy. (cutting)
|
|
|
|
23. HADOOP-636. Add MapFile & ArrayFile constructors which accept a
|
|
Progressable, and pass it down to SequenceFile. This permits
|
|
reduce tasks which use MapFile to still report progress while
|
|
writing blocks to the filesystem. (cutting)
|
|
|
|
24. HADOOP-576. Enable contrib/streaming to use the file cache. Also
|
|
extend the cache to permit symbolic links to cached items, rather
|
|
than local file copies. (Mahadev Konar via cutting)
|
|
|
|
25. HADOOP-482. Fix unit tests to work when a cluster is running on
|
|
the same machine, removing port conflicts. (Wendy Chien via cutting)
|
|
|
|
26. HADOOP-90. Permit dfs.name.dir to list multiple directories,
|
|
where namenode data is to be replicated. (Milind Bhandarkar via cutting)
|
|
|
|
27. HADOOP-651. Fix DFSCk to correctly pass parameters to the servlet
|
|
on the namenode. (Milind Bhandarkar via cutting)
|
|
|
|
28. HADOOP-553. Change main() routines of DataNode and NameNode to
|
|
log exceptions rather than letting the JVM print them to standard
|
|
error. Also, change the hadoop-daemon.sh script to rotate
|
|
standard i/o log files. (Raghu Angadi via cutting)
|
|
|
|
29. HADOOP-399. Fix javadoc warnings. (Nigel Daley via cutting)
|
|
|
|
30. HADOOP-599. Fix web ui and command line to correctly report DFS
|
|
filesystem size statistics. Also improve web layout.
|
|
(Raghu Angadi via cutting)
|
|
|
|
31. HADOOP-660. Permit specification of junit test output format.
|
|
(Nigel Daley via cutting)
|
|
|
|
32. HADOOP-663. Fix a few unit test issues. (Mahadev Konar via cutting)
|
|
|
|
33. HADOOP-664. Cause entire build to fail if libhdfs tests fail.
|
|
(Nigel Daley via cutting)
|
|
|
|
34. HADOOP-633. Keep jobtracker from dying when job initialization
|
|
throws exceptions. Also improve exception handling in a few other
|
|
places and add more informative thread names.
|
|
(omalley via cutting)
|
|
|
|
35. HADOOP-669. Fix a problem introduced by HADOOP-90 that can cause
|
|
DFS to lose files. (Milind Bhandarkar via cutting)
|
|
|
|
36. HADOOP-373. Consistently check the value returned by
|
|
FileSystem.mkdirs(). (Wendy Chien via cutting)
|
|
|
|
37. HADOOP-670. Code cleanups in some DFS internals: use generic
|
|
types, replace Vector with ArrayList, etc.
|
|
(Konstantin Shvachko via cutting)
|
|
|
|
38. HADOOP-647. Permit map outputs to use a different compression
|
|
type than the job output. (omalley via cutting)
|
|
|
|
39. HADOOP-671. Fix file cache to check for pre-existence before
|
|
creating . (Mahadev Konar via cutting)
|
|
|
|
40. HADOOP-665. Extend many DFSShell commands to accept multiple
|
|
arguments. Now commands like "ls", "rm", etc. will operate on
|
|
multiple files. (Dhruba Borthakur via cutting)
|
|
|
|
|
|
Release 0.7.2 - 2006-10-18
|
|
|
|
1. HADOOP-607. Fix a bug where classes included in job jars were not
|
|
found by tasks. (Mahadev Konar via cutting)
|
|
|
|
2. HADOOP-609. Add a unit test that checks that classes in job jars
|
|
can be found by tasks. Also modify unit tests to specify multiple
|
|
local directories. (Mahadev Konar via cutting)
|
|
|
|
|
|
Release 0.7.1 - 2006-10-11
|
|
|
|
1. HADOOP-593. Fix a NullPointerException in the JobTracker.
|
|
(omalley via cutting)
|
|
|
|
2. HADOOP-592. Fix a NullPointerException in the IPC Server. Also
|
|
consistently log when stale calls are discarded. (omalley via cutting)
|
|
|
|
3. HADOOP-594. Increase the DFS safe-mode threshold from .95 to
|
|
.999, so that nearly all blocks must be reported before filesystem
|
|
modifications are permitted. (Konstantin Shvachko via cutting)
|
|
|
|
4. HADOOP-598. Fix tasks to retry when reporting completion, so that
|
|
a single RPC timeout won't fail a task. (omalley via cutting)
|
|
|
|
5. HADOOP-597. Fix TaskTracker to not discard map outputs for errors
|
|
in transmitting them to reduce nodes. (omalley via cutting)
|
|
|
|
|
|
Release 0.7.0 - 2006-10-06
|
|
|
|
1. HADOOP-243. Fix rounding in the display of task and job progress
|
|
so that things are not shown to be 100% complete until they are in
|
|
fact finished. (omalley via cutting)
|
|
|
|
2. HADOOP-438. Limit the length of absolute paths in DFS, since the
|
|
file format used to store pathnames has some limitations.
|
|
(Wendy Chien via cutting)
|
|
|
|
3. HADOOP-530. Improve error messages in SequenceFile when keys or
|
|
values are of the wrong type. (Hairong Kuang via cutting)
|
|
|
|
4. HADOOP-288. Add a file caching system and use it in MapReduce to
|
|
cache job jar files on slave nodes. (Mahadev Konar via cutting)
|
|
|
|
5. HADOOP-533. Fix unit test to not modify conf directory.
|
|
(Hairong Kuang via cutting)
|
|
|
|
6. HADOOP-527. Permit specification of the local address that various
|
|
Hadoop daemons should bind to. (Philippe Gassmann via cutting)
|
|
|
|
7. HADOOP-542. Updates to contrib/streaming: reformatted source code,
|
|
on-the-fly merge sort, a fix for HADOOP-540, etc.
|
|
(Michel Tourn via cutting)
|
|
|
|
8. HADOOP-545. Remove an unused config file parameter.
|
|
(Philippe Gassmann via cutting)
|
|
|
|
9. HADOOP-548. Add an Ant property "test.output" to build.xml that
|
|
causes test output to be logged to the console. (omalley via cutting)
|
|
|
|
10. HADOOP-261. Record an error message when map output is lost.
|
|
(omalley via cutting)
|
|
|
|
11. HADOOP-293. Report the full list of task error messages in the
|
|
web ui, not just the most recent. (omalley via cutting)
|
|
|
|
12. HADOOP-551. Restore JobClient's console printouts to only include
|
|
a maximum of one update per one percent of progress.
|
|
(omalley via cutting)
|
|
|
|
13. HADOOP-306. Add a "safe" mode to DFS. The name node enters this
|
|
when less than a specified percentage of file data is complete.
|
|
Currently safe mode is only used on startup, but eventually it
|
|
will also be entered when datanodes disconnect and file data
|
|
becomes incomplete. While in safe mode no filesystem
|
|
modifications are permitted and block replication is inhibited.
|
|
(Konstantin Shvachko via cutting)
|
|
|
|
14. HADOOP-431. Change 'dfs -rm' to not operate recursively and add a
|
|
new command, 'dfs -rmr' which operates recursively.
|
|
(Sameer Paranjpye via cutting)
|
|
|
|
15. HADOOP-263. Include timestamps for job transitions. The web
|
|
interface now displays the start and end times of tasks and the
|
|
start times of sorting and reducing for reduce tasks. Also,
|
|
extend ObjectWritable to handle enums, so that they can be passed
|
|
as RPC parameters. (Sanjay Dahiya via cutting)
|
|
|
|
16. HADOOP-556. Contrib/streaming: send keep-alive reports to task
|
|
tracker every 10 seconds rather than every 100 records, to avoid
|
|
task timeouts. (Michel Tourn via cutting)
|
|
|
|
17. HADOOP-547. Fix reduce tasks to ping tasktracker while copying
|
|
data, rather than only between copies, avoiding task timeouts.
|
|
(Sanjay Dahiya via cutting)
|
|
|
|
18. HADOOP-537. Fix src/c++/libhdfs build process to create files in
|
|
build/, no longer modifying the source tree.
|
|
(Arun C Murthy via cutting)
|
|
|
|
19. HADOOP-487. Throw a more informative exception for unknown RPC
|
|
hosts. (Sameer Paranjpye via cutting)
|
|
|
|
20. HADOOP-559. Add file name globbing (pattern matching) support to
|
|
the FileSystem API, and use it in DFSShell ('bin/hadoop dfs')
|
|
commands. (Hairong Kuang via cutting)
|
|
|
|
21. HADOOP-508. Fix a bug in FSDataInputStream. Incorrect data was
|
|
returned after seeking to a random location.
|
|
(Milind Bhandarkar via cutting)
|
|
|
|
22. HADOOP-560. Add a "killed" task state. This can be used to
|
|
distinguish kills from other failures. Task state has also been
|
|
converted to use an enum type instead of an int, uncovering a bug
|
|
elsewhere. The web interface is also updated to display killed
|
|
tasks. (omalley via cutting)
|
|
|
|
23. HADOOP-423. Normalize Paths containing directories named "." and
|
|
"..", using the standard, unix interpretation. Also add checks in
|
|
DFS, prohibiting the use of "." or ".." as directory or file
|
|
names. (Wendy Chien via cutting)
|
|
|
|
24. HADOOP-513. Replace map output handling with a servlet, rather
|
|
than a JSP page. This fixes an issue where
|
|
IllegalStateException's were logged, sets content-length
|
|
correctly, and better handles some errors. (omalley via cutting)
|
|
|
|
25. HADOOP-552. Improved error checking when copying map output files
|
|
to reduce nodes. (omalley via cutting)
|
|
|
|
26. HADOOP-566. Fix scripts to work correctly when accessed through
|
|
relative symbolic links. (Lee Faris via cutting)
|
|
|
|
27. HADOOP-519. Add positioned read methods to FSInputStream. These
|
|
permit one to read from a stream without moving its position, and
|
|
can hence be performed by multiple threads at once on a single
|
|
stream. Implement an optimized version for DFS and local FS.
|
|
(Milind Bhandarkar via cutting)
|
|
|
|
28. HADOOP-522. Permit block compression with MapFile and SetFile.
|
|
Since these formats are always sorted, block compression can
|
|
provide a big advantage. (cutting)
|
|
|
|
29. HADOOP-567. Record version and revision information in builds. A
|
|
package manifest is added to the generated jar file containing
|
|
version information, and a VersionInfo utility is added that
|
|
includes further information, including the build date and user,
|
|
and the subversion revision and repository. A 'bin/hadoop
|
|
version' comand is added to show this information, and it is also
|
|
added to various web interfaces. (omalley via cutting)
|
|
|
|
30. HADOOP-568. Fix so that errors while initializing tasks on a
|
|
tasktracker correctly report the task as failed to the jobtracker,
|
|
so that it will be rescheduled. (omalley via cutting)
|
|
|
|
31. HADOOP-550. Disable automatic UTF-8 validation in Text. This
|
|
permits, e.g., TextInputFormat to again operate on non-UTF-8 data.
|
|
(Hairong and Mahadev via cutting)
|
|
|
|
32. HADOOP-343. Fix mapred copying so that a failed tasktracker
|
|
doesn't cause other copies to slow. (Sameer Paranjpye via cutting)
|
|
|
|
33. HADOOP-239. Add a persistent job history mechanism, so that basic
|
|
job statistics are not lost after 24 hours and/or when the
|
|
jobtracker is restarted. (Sanjay Dahiya via cutting)
|
|
|
|
34. HADOOP-506. Ignore heartbeats from stale task trackers.
|
|
(Sanjay Dahiya via cutting)
|
|
|
|
35. HADOOP-255. Discard stale, queued IPC calls. Do not process
|
|
calls whose clients will likely time out before they receive a
|
|
response. When the queue is full, new calls are now received and
|
|
queued, and the oldest calls are discarded, so that, when servers
|
|
get bogged down, they no longer develop a backlog on the socket.
|
|
This should improve some DFS namenode failure modes.
|
|
(omalley via cutting)
|
|
|
|
36. HADOOP-581. Fix datanode to not reset itself on communications
|
|
errors with the namenode. If a request to the namenode fails, the
|
|
datanode should retry, not restart. This reduces the load on the
|
|
namenode, since restarts cause a resend of the block report.

Release 0.6.2 - 2006-09-18
|
|
|
|
1. HADOOP-532. Fix a bug reading value-compressed sequence files,
|
|
where an exception was thrown reporting that the full value had not
|
|
been read. (omalley via cutting)
|
|
|
|
2. HADOOP-534. Change the default value class in JobConf to be Text
|
|
instead of the now-deprecated UTF8. This fixes the Grep example
|
|
program, which was updated to use Text, but relies on this
|
|
default. (Hairong Kuang via cutting)
|
|
|
|
|
|
Release 0.6.1 - 2006-09-13
|
|
|
|
1. HADOOP-520. Fix a bug in libhdfs, where write failures were not
|
|
correctly returning error codes. (Arun C Murthy via cutting)
|
|
|
|
2. HADOOP-523. Fix a NullPointerException when TextInputFormat is
|
|
explicitly specified. Also add a test case for this.
|
|
(omalley via cutting)
|
|
|
|
3. HADOOP-521. Fix another NullPointerException finding the
|
|
ClassLoader when using libhdfs. (omalley via cutting)
|
|
|
|
4. HADOOP-526. Fix a NullPointerException when attempting to start
|
|
two datanodes in the same directory. (Milind Bhandarkar via cutting)
|
|
|
|
5. HADOOP-529. Fix a NullPointerException when opening
|
|
value-compressed sequence files generated by pre-0.6.0 Hadoop.
|
|
(omalley via cutting)
|
|
|
|
|
|
Release 0.6.0 - 2006-09-08
|
|
|
|
1. HADOOP-427. Replace some uses of DatanodeDescriptor in the DFS
|
|
web UI code with DatanodeInfo, the preferred public class.
|
|
(Devaraj Das via cutting)
|
|
|
|
2. HADOOP-426. Fix streaming contrib module to work correctly on
|
|
Solaris. This was causing nightly builds to fail.
|
|
(Michel Tourn via cutting)
|
|
|
|
3. HADOOP-400. Improvements to task assignment. Tasks are no longer
|
|
re-run on nodes where they have failed (unless no other node is
|
|
available). Also, tasks are better load-balanced among nodes.
|
|
(omalley via cutting)
|
|
|
|
4. HADOOP-324. Fix datanode to not exit when a disk is full, but
|
|
rather simply to fail writes. (Wendy Chien via cutting)
|
|
|
|
5. HADOOP-434. Change smallJobsBenchmark to use standard Hadoop
|
|
scripts. (Sanjay Dahiya via cutting)
|
|
|
|
6. HADOOP-453. Fix a bug in Text.setCapacity(). (siren via cutting)
|
|
|
|
|
|
7. HADOOP-450. Change so that input types are determined by the
|
|
RecordReader rather than specified directly in the JobConf. This
|
|
facilitates jobs with a variety of input types.
|
|
|
|
WARNING: This contains incompatible API changes! The RecordReader
|
|
interface has two new methods that all user-defined InputFormats
|
|
must now define. Also, the values returned by TextInputFormat are
|
|
no longer of class UTF8, but now of class Text.
|
|
|
|
8. HADOOP-436. Fix an error-handling bug in the web ui.
|
|
(Devaraj Das via cutting)
|
|
|
|
9. HADOOP-455. Fix a bug in Text, where DEL was not permitted.
|
|
(Hairong Kuang via cutting)
|
|
|
|
10. HADOOP-456. Change the DFS namenode to keep a persistent record
|
|
of the set of known datanodes. This will be used to implement a
|
|
"safe mode" where filesystem changes are prohibited when a
|
|
critical percentage of the datanodes are unavailable.
|
|
(Konstantin Shvachko via cutting)
|
|
|
|
11. HADOOP-322. Add a job control utility. This permits one to
|
|
specify job interdependencies. Each job is submitted only after
|
|
the jobs it depends on have successfully completed.
|
|
(Runping Qi via cutting)
|
|
|
|
12. HADOOP-176. Fix a bug in IntWritable.Comparator.
|
|
(Dick King via cutting)
|
|
|
|
13. HADOOP-421. Replace uses of String in recordio package with Text
|
|
class, for improved handling of UTF-8 data.
|
|
(Milind Bhandarkar via cutting)
|
|
|
|
14. HADOOP-464. Improved error message when job jar not found.
|
|
(Michel Tourn via cutting)
|
|
|
|
15. HADOOP-469. Fix /bin/bash specifics that have crept into our
|
|
/bin/sh scripts since HADOOP-352.
|
|
(Jean-Baptiste Quenot via cutting)
|
|
|
|
16. HADOOP-468. Add HADOOP_NICENESS environment variable to set
|
|
scheduling priority for daemons. (Vetle Roeim via cutting)
|
|
|
|
17. HADOOP-473. Fix TextInputFormat to correctly handle more EOL
|
|
formats. Things now work correctly with CR, LF or CRLF.
|
|
(Dennis Kubes & James White via cutting)
|
|
|
|
18. HADOOP-461. Make Java 1.5 an explicit requirement. (cutting)
|
|
|
|
19. HADOOP-54. Add block compression to SequenceFile. One may now
|
|
specify that blocks of keys and values are compressed together,
|
|
improving compression for small keys and values.
|
|
SequenceFile.Writer's constructor is now deprecated and replaced
|
|
with a factory method. (Arun C Murthy via cutting)
|
|
|
|
20. HADOOP-281. Prohibit DFS files that are also directories.
|
|
(Wendy Chien via cutting)
|
|
|
|
21. HADOOP-486. Add the job username to JobStatus instances returned
|
|
by JobClient. (Mahadev Konar via cutting)
|
|
|
|
22. HADOOP-437. contrib/streaming: Add support for gzipped inputs.
|
|
(Michel Tourn via cutting)
|
|
|
|
23. HADOOP-463. Add variable expansion to config files.
|
|
Configuration property values may now contain variable
|
|
expressions. A variable is referenced with the syntax
|
|
'${variable}'. Variables values are found first in the
|
|
configuration, and then in Java system properties. The default
|
|
configuration is modified so that temporary directories are now
|
|
under ${hadoop.tmp.dir}, which is, by default,
|
|
/tmp/hadoop-${user.name}. (Michel Tourn via cutting)
|
|
|
|
24. HADOOP-419. Fix a NullPointerException finding the ClassLoader
|
|
when using libhdfs. (omalley via cutting)
|
|
|
|
25. HADOOP-460. Fix contrib/smallJobsBenchmark to use Text instead of
|
|
UTF8. (Sanjay Dahiya via cutting)
|
|
|
|
26. HADOOP-196. Fix Configuration(Configuration) constructor to work
|
|
correctly. (Sami Siren via cutting)
|
|
|
|
27. HADOOP-501. Fix Configuration.toString() to handle URL resources.
|
|
(Thomas Friol via cutting)
|
|
|
|
28. HADOOP-499. Reduce the use of Strings in contrib/streaming,
|
|
replacing them with Text for better performance.
|
|
(Hairong Kuang via cutting)
|
|
|
|
29. HADOOP-64. Manage multiple volumes with a single DataNode.
|
|
Previously DataNode would create a separate daemon per configured
|
|
volume, each with its own connection to the NameNode. Now all
|
|
volumes are handled by a single DataNode daemon, reducing the load
|
|
on the NameNode. (Milind Bhandarkar via cutting)
|
|
|
|
30. HADOOP-424. Fix MapReduce so that jobs which generate zero splits
|
|
do not fail. (Fr??d??ric Bertin via cutting)
|
|
|
|
31. HADOOP-408. Adjust some timeouts and remove some others so that
|
|
unit tests run faster. (cutting)
|
|
|
|
32. HADOOP-507. Fix an IllegalAccessException in DFS.
|
|
(omalley via cutting)
|
|
|
|
33. HADOOP-320. Fix so that checksum files are correctly copied when
|
|
the destination of a file copy is a directory.
|
|
(Hairong Kuang via cutting)
|
|
|
|
34. HADOOP-286. In DFSClient, avoid pinging the NameNode with
|
|
renewLease() calls when no files are being written.
|
|
(Konstantin Shvachko via cutting)
|
|
|
|
35. HADOOP-312. Close idle IPC connections. All IPC connections were
|
|
cached forever. Now, after a connection has been idle for more
|
|
than a configurable amount of time (one second by default), the
|
|
connection is closed, conserving resources on both client and
|
|
server. (Devaraj Das via cutting)
|
|
|
|
36. HADOOP-497. Permit the specification of the network interface and
|
|
nameserver to be used when determining the local hostname
|
|
advertised by datanodes and tasktrackers.
|
|
(Lorenzo Thione via cutting)
|
|
|
|
37. HADOOP-441. Add a compression codec API and extend SequenceFile
|
|
to use it. This will permit the use of alternate compression
|
|
codecs in SequenceFile. (Arun C Murthy via cutting)
|
|
|
|
38. HADOOP-483. Improvements to libhdfs build and documentation.
|
|
(Arun C Murthy via cutting)
|
|
|
|
39. HADOOP-458. Fix a memory corruption bug in libhdfs.
|
|
(Arun C Murthy via cutting)
|
|
|
|
40. HADOOP-517. Fix a contrib/streaming bug in end-of-line detection.
|
|
(Hairong Kuang via cutting)
|
|
|
|
41. HADOOP-474. Add CompressionCodecFactory, and use it in
|
|
TextInputFormat and TextOutputFormat. Compressed input files are
|
|
automatically decompressed when they have the correct extension.
|
|
Output files will, when output compression is specified, be
|
|
generated with an approprate extension. Also add a gzip codec and
|
|
fix problems with UTF8 text inputs. (omalley via cutting)
|
|
|
|
|
|
Release 0.5.0 - 2006-08-04
|
|
|
|
1. HADOOP-352. Fix shell scripts to use /bin/sh instead of
|
|
/bin/bash, for better portability.
|
|
(Jean-Baptiste Quenot via cutting)
|
|
|
|
2. HADOOP-313. Permit task state to be saved so that single tasks
|
|
may be manually re-executed when debugging. (omalley via cutting)
|
|
|
|
3. HADOOP-339. Add method to JobClient API listing jobs that are
|
|
not yet complete, i.e., that are queued or running.
|
|
(Mahadev Konar via cutting)
|
|
|
|
4. HADOOP-355. Updates to the streaming contrib module, including
|
|
API fixes, making reduce optional, and adding an input type for
|
|
StreamSequenceRecordReader. (Michel Tourn via cutting)
|
|
|
|
5. HADOOP-358. Fix a NPE bug in Path.equals().
|
|
(Fr??d??ric Bertin via cutting)
|
|
|
|
6. HADOOP-327. Fix ToolBase to not call System.exit() when
|
|
exceptions are thrown. (Hairong Kuang via cutting)
|
|
|
|
7. HADOOP-359. Permit map output to be compressed.
|
|
(omalley via cutting)
|
|
|
|
8. HADOOP-341. Permit input URI to CopyFiles to use the HTTP
|
|
protocol. This lets one, e.g., more easily copy log files into
|
|
DFS. (Arun C Murthy via cutting)
|
|
|
|
9. HADOOP-361. Remove unix dependencies from streaming contrib
|
|
module tests, making them pure java. (Michel Tourn via cutting)
|
|
|
|
10. HADOOP-354. Make public methods to stop DFS daemons.
|
|
(Barry Kaplan via cutting)
|
|
|
|
11. HADOOP-252. Add versioning to RPC protocols.
|
|
(Milind Bhandarkar via cutting)
|
|
|
|
12. HADOOP-356. Add contrib to "compile" and "test" build targets, so
|
|
that this code is better maintained. (Michel Tourn via cutting)
|
|
|
|
13. HADOOP-307. Add smallJobsBenchmark contrib module. This runs
|
|
lots of small jobs, in order to determine per-task overheads.
|
|
(Sanjay Dahiya via cutting)
|
|
|
|
14. HADOOP-342. Add a tool for log analysis: Logalyzer.
|
|
(Arun C Murthy via cutting)
|
|
|
|
15. HADOOP-347. Add web-based browsing of DFS content. The namenode
|
|
redirects browsing requests to datanodes. Content requests are
|
|
redirected to datanodes where the data is local when possible.
|
|
(Devaraj Das via cutting)
|
|
|
|
16. HADOOP-351. Make Hadoop IPC kernel independent of Jetty.
|
|
(Devaraj Das via cutting)
|
|
|
|
17. HADOOP-237. Add metric reporting to DFS and MapReduce. With only
|
|
minor configuration changes, one can now monitor many Hadoop
|
|
system statistics using Ganglia or other monitoring systems.
|
|
(Milind Bhandarkar via cutting)
|
|
|
|
18. HADOOP-376. Fix datanode's HTTP server to scan for a free port.
|
|
(omalley via cutting)
|
|
|
|
19. HADOOP-260. Add --config option to shell scripts, specifying an
|
|
alternate configuration directory. (Milind Bhandarkar via cutting)
|
|
|
|
20. HADOOP-381. Permit developers to save the temporary files for
|
|
tasks whose names match a regular expression, to facilliate
|
|
debugging. (omalley via cutting)
|
|
|
|
21. HADOOP-344. Fix some Windows-related problems with DF.
|
|
(Konstantin Shvachko via cutting)
|

|
|
outputs. (Mahadev Konar via cutting)
|
|
|
|
23. HADOOP-321. Refactor DatanodeInfo, in preparation for
|
|
HADOOP-306. (Konstantin Shvachko & omalley via cutting)
|
|
|
|
24. HADOOP-385. Fix some bugs in record io code generation.
|
|
(Milind Bhandarkar via cutting)
|
|
|
|
25. HADOOP-302. Add new Text class to replace UTF8, removing
|
|
limitations of that class. Also refactor utility methods for
|
|
writing zero-compressed integers (VInts and VLongs).
|
|
(Hairong Kuang via cutting)
|
|
|
|
26. HADOOP-335. Refactor DFS namespace/transaction logging in
|
|
namenode. (Konstantin Shvachko via cutting)
|
|
|
|
27. HADOOP-375. Fix handling of the datanode HTTP daemon's port so
|
|
that multiple datanode's can be run on a single host.
|
|
(Devaraj Das via cutting)
|
|
|
|
28. HADOOP-386. When removing excess DFS block replicas, remove those
|
|
on nodes with the least free space first.
|
|
(Johan Oskarson via cutting)
|
|
|
|
29. HADOOP-389. Fix intermittent failures of mapreduce unit tests.
|
|
Also fix some build dependencies.
|
|
(Mahadev & Konstantin via cutting)
|
|
|
|
30. HADOOP-362. Fix a problem where jobs hang when status messages
|
|
are recieved out-of-order. (omalley via cutting)
|
|
|
|
31. HADOOP-394. Change order of DFS shutdown in unit tests to
|
|
minimize errors logged. (Konstantin Shvachko via cutting)
|
|
|
|
32. HADOOP-396. Make DatanodeID implement Writable.
|
|
(Konstantin Shvachko via cutting)
|
|
|
|
33. HADOOP-377. Permit one to add URL resources to a Configuration.
|
|
(Jean-Baptiste Quenot via cutting)
|
|
|
|
34. HADOOP-345. Permit iteration over Configuration key/value pairs.
|
|
(Michel Tourn via cutting)
|
|
|
|
35. HADOOP-409. Streaming contrib module: make configuration
|
|
properties available to commands as environment variables.
|
|
(Michel Tourn via cutting)
|

|
|
36. HADOOP-369. Add -getmerge option to dfs command that appends all
|
|
files in a directory into a single local file.
|
|
(Johan Oskarson via cutting)
|
|
|
|
37. HADOOP-410. Replace some TreeMaps with HashMaps in DFS, for
|
|
a 17% performance improvement. (Milind Bhandarkar via cutting)
|
|
|
|
38. HADOOP-411. Add unit tests for command line parser.
|
|
(Hairong Kuang via cutting)
|
|
|
|
39. HADOOP-412. Add MapReduce input formats that support filtering
|
|
of SequenceFile data, including sampling and regex matching.
|
|
Also, move JobConf.newInstance() to a new utility class.
|
|
(Hairong Kuang via cutting)
|
|
|
|
40. HADOOP-226. Fix fsck command to properly consider replication
|
|
counts, now that these can vary per file. (Bryan Pendleton via cutting)
|
|
|
|
41. HADOOP-425. Add a Python MapReduce example, using Jython.
|
|
(omalley via cutting)
|
|
|
|
|
|
Release 0.4.0 - 2006-06-28
|
|
|
|
1. HADOOP-298. Improved progress reports for CopyFiles utility, the
|
|
distributed file copier. (omalley via cutting)
|
|
|
|
2. HADOOP-299. Fix the task tracker, permitting multiple jobs to
|
|
more easily execute at the same time. (omalley via cutting)
|
|
|
|
3. HADOOP-250. Add an HTTP user interface to the namenode, running
|
|
on port 50070. (Devaraj Das via cutting)
|
|
|
|
4. HADOOP-123. Add MapReduce unit tests that run a jobtracker and
|
|
tasktracker, greatly increasing code coverage.
|
|
(Milind Bhandarkar via cutting)
|
|
|
|
5. HADOOP-271. Add links from jobtracker's web ui to tasktracker's
|
|
web ui. Also attempt to log a thread dump of child processes
|
|
before they're killed. (omalley via cutting)
|
|
|
|
6. HADOOP-210. Change RPC server to use a selector instead of a
|
|
thread per connection. This should make it easier to scale to
|
|
larger clusters. Note that this incompatibly changes the RPC
|
|
protocol: clients and servers must both be upgraded to the new
|
|
version to ensure correct operation. (Devaraj Das via cutting)
|
|
|
|
7. HADOOP-311. Change DFS client to retry failed reads, so that a
|
|
single read failure will not alone cause failure of a task.
|
|
(omalley via cutting)
|
|
|
|
8. HADOOP-314. Remove the "append" phase when reducing. Map output
|
|
files are now directly passed to the sorter, without first
|
|
appending them into a single file. Now, the first third of reduce
|
|
progress is "copy" (transferring map output to reduce nodes), the
|
|
middle third is "sort" (sorting map output) and the last third is
|
|
"reduce" (generating output). Long-term, the "sort" phase will
|
|
also be removed. (omalley via cutting)
|
|
|
|
9. HADOOP-316. Fix a potential deadlock in the jobtracker.
|
|
(omalley via cutting)
|
|
|
|
10. HADOOP-319. Fix FileSystem.close() to remove the FileSystem
|
|
instance from the cache. (Hairong Kuang via cutting)
|
|
|
|
11. HADOOP-135. Fix potential deadlock in JobTracker by acquiring
|
|
locks in a consistent order. (omalley via cutting)
|
|
|
|
12. HADOOP-278. Check for existence of input directories before
|
|
starting MapReduce jobs, making it easier to debug this common
|
|
error. (omalley via cutting)
|
|
|
|
13. HADOOP-304. Improve error message for
|
|
UnregisterdDatanodeException to include expected node name.
|
|
(Konstantin Shvachko via cutting)
|
|
|
|
14. HADOOP-305. Fix TaskTracker to ask for new tasks as soon as a
|
|
task is finished, rather than waiting for the next heartbeat.
|
|
This improves performance when tasks are short.
|
|
(Mahadev Konar via cutting)
|
|
|
|
15. HADOOP-59. Add support for generic command line options. One may
|
|
now specify the filesystem (-fs), the MapReduce jobtracker (-jt),
|
|
a config file (-conf) or any configuration property (-D). The
|
|
"dfs", "fsck", "job", and "distcp" commands currently support
|
|
this, with more to be added. (Hairong Kuang via cutting)
|
|
|
|
16. HADOOP-296. Permit specification of the amount of reserved space
|
|
on a DFS datanode. One may specify both the percentage free and
|
|
the number of bytes. (Johan Oskarson via cutting)
|
|
|
|
17. HADOOP-325. Fix a problem initializing RPC parameter classes, and
|
|
remove the workaround used to initialize classes.
|
|
(omalley via cutting)
|
|
|
|
18. HADOOP-328. Add an option to the "distcp" command to ignore read
|
|
errors while copying. (omalley via cutting)
|
|
|
|
19. HADOOP-27. Don't allocate tasks to trackers whose local free
|
|
space is too low. (Johan Oskarson via cutting)
|
|
|
|
20. HADOOP-318. Keep slow DFS output from causing task timeouts.
|
|
This incompatibly changes some public interfaces, adding a
|
|
parameter to OutputFormat.getRecordWriter() and the new method
|
|
Reporter.progress(), but it makes lots of tasks succeed that were
|
|
previously failing. (Milind Bhandarkar via cutting)
|
|
|
|
|
|
Release 0.3.2 - 2006-06-09
|
|
|
|
1. HADOOP-275. Update the streaming contrib module to use log4j for
|
|
its logging. (Michel Tourn via cutting)
|
|
|
|
2. HADOOP-279. Provide defaults for log4j logging parameters, so
|
|
that things still work reasonably when Hadoop-specific system
|
|
properties are not provided. (omalley via cutting)
|
|
|
|
3. HADOOP-280. Fix a typo in AllTestDriver which caused the wrong
|
|
test to be run when "DistributedFSCheck" was specified.
|
|
(Konstantin Shvachko via cutting)
|
|
|
|
4. HADOOP-240. DFS's mkdirs() implementation no longer logs a warning
|
|
when the directory already exists. (Hairong Kuang via cutting)
|
|
|
|
5. HADOOP-285. Fix DFS datanodes to be able to re-join the cluster
|
|
after the connection to the namenode is lost. (omalley via cutting)
|
|
|
|
6. HADOOP-277. Fix a race condition when creating directories.
|
|
(Sameer Paranjpye via cutting)
|
|
|
|
7. HADOOP-289. Improved exception handling in DFS datanode.
|
|
(Konstantin Shvachko via cutting)
|
|
|
|
8. HADOOP-292. Fix client-side logging to go to standard error
|
|
rather than standard output, so that it can be distinguished from
|
|
application output. (omalley via cutting)
|
|
|
|
9. HADOOP-294. Fixed bug where conditions for retrying after errors
|
|
in the DFS client were reversed. (omalley via cutting)
|
|
|
|
|
|
Release 0.3.1 - 2006-06-05
|
|
|
|
1. HADOOP-272. Fix a bug in bin/hadoop setting log
|
|
parameters. (omalley & cutting)
|
|
|
|
2. HADOOP-274. Change applications to log to standard output rather
|
|
than to a rolling log file like daemons. (omalley via cutting)
|
|
|
|
3. HADOOP-262. Fix reduce tasks to report progress while they're
|
|
waiting for map outputs, so that they do not time out.
|
|
(Mahadev Konar via cutting)
|
|
|
|
4. HADOOP-245 and HADOOP-246. Improvements to record io package.
|
|
(Mahadev Konar via cutting)
|
|
|
|
5. HADOOP-276. Add logging config files to jar file so that they're
|
|
always found. (omalley via cutting)
|
|
|
|
|
|
Release 0.3.0 - 2006-06-02
|
|
|
|
1. HADOOP-208. Enhance MapReduce web interface, adding new pages
|
|
for failed tasks, and tasktrackers. (omalley via cutting)
|
|
|
|
2. HADOOP-204. Tweaks to metrics package. (David Bowen via cutting)
|
|
|
|
3. HADOOP-209. Add a MapReduce-based file copier. This will
|
|
copy files within or between file systems in parallel.
|
|
(Milind Bhandarkar via cutting)
|
|
|
|
4. HADOOP-146. Fix DFS to check when randomly generating a new block
|
|
id that no existing blocks already have that id.
|
|
(Milind Bhandarkar via cutting)
|
|
|
|
5. HADOOP-180. Make a daemon thread that does the actual task clean ups, so
|
|
that the main offerService thread in the taskTracker doesn't get stuck
|
|
and miss his heartbeat window. This was killing many task trackers as
|
|
big jobs finished (300+ tasks / node). (omalley via cutting)
|
|
|
|
6. HADOOP-200. Avoid transmitting entire list of map task names to
|
|
reduce tasks. Instead just transmit the number of map tasks and
|
|
henceforth refer to them by number when collecting map output.
|
|
(omalley via cutting)
|
|
|
|
7. HADOOP-219. Fix a NullPointerException when handling a checksum
|
|
exception under SequenceFile.Sorter.sort(). (cutting & stack)
|
|
|
|
8. HADOOP-212. Permit alteration of the file block size in DFS. The
|
|
default block size for new files may now be specified in the
|
|
configuration with the dfs.block.size property. The block size
|
|
may also be specified when files are opened.
|
|
(omalley via cutting)
|
|
|
|
9. HADOOP-218. Avoid accessing configuration while looping through
|
|
tasks in JobTracker. (Mahadev Konar via cutting)
|
|
|
|
10. HADOOP-161. Add hashCode() method to DFS's Block.
|
|
(Milind Bhandarkar via cutting)
|
|
|
|
11. HADOOP-115. Map output types may now be specified. These are also
|
|
used as reduce input types, thus permitting reduce input types to
|
|
differ from reduce output types. (Runping Qi via cutting)
|
|
|
|
12. HADOOP-216. Add task progress to task status page.
|
|
(Bryan Pendelton via cutting)
|
|
|
|
13. HADOOP-233. Add web server to task tracker that shows running
|
|
tasks and logs. Also add log access to job tracker web interface.
|
|
(omalley via cutting)
|
|
|
|
14. HADOOP-205. Incorporate pending tasks into tasktracker load
|
|
calculations. (Mahadev Konar via cutting)
|
|
|
|
15. HADOOP-247. Fix sort progress to better handle exceptions.
|
|
(Mahadev Konar via cutting)
|
|
|
|
16. HADOOP-195. Improve performance of the transfer of map outputs to
|
|
reduce nodes by performing multiple transfers in parallel, each on
|
|
a separate socket. (Sameer Paranjpye via cutting)
|
|
|
|
17. HADOOP-251. Fix task processes to be tolerant of failed progress
|
|
reports to their parent process. (omalley via cutting)
|
|
|
|
18. HADOOP-325. Improve the FileNotFound exceptions thrown by
|
|
LocalFileSystem to include the name of the file.
|
|
(Benjamin Reed via cutting)
|
|
|
|
19. HADOOP-254. Use HTTP to transfer map output data to reduce
|
|
nodes. This, together with HADOOP-195, greatly improves the
|
|
performance of these transfers. (omalley via cutting)
|
|
|
|
20. HADOOP-163. Cause datanodes that\ are unable to either read or
|
|
write data to exit, so that the namenode will no longer target
|
|
them for new blocks and will replicate their data on other nodes.
|
|
(Hairong Kuang via cutting)
|
|
|
|
21. HADOOP-222. Add a -setrep option to the dfs commands that alters
|
|
file replication levels. (Johan Oskarson via cutting)
|
|
|
|
22. HADOOP-75. In DFS, only check for a complete file when the file
|
|
is closed, rather than as each block is written.
|
|
(Milind Bhandarkar via cutting)
|
|
|
|
23. HADOOP-124. Change DFS so that datanodes are identified by a
|
|
persistent ID rather than by host and port. This solves a number
|
|
of filesystem integrity problems, when, e.g., datanodes are
|
|
restarted. (Konstantin Shvachko via cutting)
|
|
|
|
24. HADOOP-256. Add a C API for DFS. (Arun C Murthy via cutting)
|
|
|
|
25. HADOOP-211. Switch to use the Jakarta Commons logging internally,
|
|
configured to use log4j by default. (Arun C Murthy and cutting)
|
|
|
|
26. HADOOP-265. Tasktracker now fails to start if it does not have a
|
|
writable local directory for temporary files. In this case, it
|
|
logs a message to the JobTracker and exits. (Hairong Kuang via cutting)
|
|
|
|
27. HADOOP-270. Fix potential deadlock in datanode shutdown.
|
|
(Hairong Kuang via cutting)
|
|
|
|
Release 0.2.1 - 2006-05-12
|
|
|
|
1. HADOOP-199. Fix reduce progress (broken by HADOOP-182).
|
|
(omalley via cutting)
|
|
|
|
2. HADOOP-201. Fix 'bin/hadoop dfs -report'. (cutting)
|
|
|
|
3. HADOOP-207. Fix JDK 1.4 incompatibility introduced by HADOOP-96.
|
|
System.getenv() does not work in JDK 1.4. (Hairong Kuang via cutting)
|
|
|
|
|
|
Release 0.2.0 - 2006-05-05
|
|
|
|
1. Fix HADOOP-126. 'bin/hadoop dfs -cp' now correctly copies .crc
|
|
files. (Konstantin Shvachko via cutting)
|
|
|
|
2. Fix HADOOP-51. Change DFS to support per-file replication counts.
|
|
(Konstantin Shvachko via cutting)
|
|
|
|
3. Fix HADOOP-131. Add scripts to start/stop dfs and mapred daemons.
|
|
Use these in start/stop-all scripts. (Chris Mattmann via cutting)
|
|
|
|
4. Stop using ssh options by default that are not yet in widely used
|
|
versions of ssh. Folks can still enable their use by uncommenting
|
|
a line in conf/hadoop-env.sh. (cutting)
|
|
|
|
5. Fix HADOOP-92. Show information about all attempts to run each
|
|
task in the web ui. (Mahadev konar via cutting)
|
|
|
|
6. Fix HADOOP-128. Improved DFS error handling. (Owen O'Malley via cutting)
|
|
|
|
7. Fix HADOOP-129. Replace uses of java.io.File with new class named
|
|
Path. This fixes bugs where java.io.File methods were called
|
|
directly when FileSystem methods were desired, and reduces the
|
|
likelihood of such bugs in the future. It also makes the handling
|
|
of pathnames more consistent between local and dfs FileSystems and
|
|
between Windows and Unix. java.io.File-based methods are still
|
|
available for back-compatibility, but are deprecated and will be
|
|
removed once 0.2 is released. (cutting)
|
|
|
|
8. Change dfs.data.dir and mapred.local.dir to be comma-separated
|
|
lists of directories, no longer be space-separated. This fixes
|
|
several bugs on Windows. (cutting)
|
|
|
|
9. Fix HADOOP-144. Use mapred task id for dfs client id, to
|
|
facilitate debugging. (omalley via cutting)
|
|
|
|
10. Fix HADOOP-143. Do not line-wrap stack-traces in web ui.
|
|
(omalley via cutting)
|
|
|
|
11. Fix HADOOP-118. In DFS, improve clean up of abandoned file
|
|
creations. (omalley via cutting)
|
|
|
|
12. Fix HADOOP-138. Stop multiple tasks in a single heartbeat, rather
|
|
than one per heartbeat. (Stefan via cutting)
|
|
|
|
13. Fix HADOOP-139. Remove a potential deadlock in
|
|
LocalFileSystem.lock(). (Igor Bolotin via cutting)
|
|
|
|
14. Fix HADOOP-134. Don't hang jobs when the tasktracker is
|
|
misconfigured to use an un-writable local directory. (omalley via cutting)
|
|
|
|
15. Fix HADOOP-115. Correct an error message. (Stack via cutting)
|
|
|
|
16. Fix HADOOP-133. Retry pings from child to parent, in case of
|
|
(local) communcation problems. Also log exit status, so that one
|
|
can distinguish patricide from other deaths. (omalley via cutting)
|
|
|
|
17. Fix HADOOP-142. Avoid re-running a task on a host where it has
|
|
previously failed. (omalley via cutting)
|
|
|
|
18. Fix HADOOP-148. Maintain a task failure count for each
|
|
tasktracker and display it in the web ui. (omalley via cutting)
|
|
|
|
19. Fix HADOOP-151. Close a potential socket leak, where new IPC
|
|
connection pools were created per configuration instance that RPCs
|
|
use. Now a global RPC connection pool is used again, as
|
|
originally intended. (cutting)
|
|
|
|
20. Fix HADOOP-69. Don't throw a NullPointerException when getting
|
|
hints for non-existing file split. (Bryan Pendelton via cutting)
|
|
|
|
21. Fix HADOOP-157. When a task that writes dfs files (e.g., a reduce
|
|
task) failed and was retried, it would fail again and again,
|
|
eventually failing the job. The problem was that dfs did not yet
|
|
know that the failed task had abandoned the files, and would not
|
|
yet let another task create files with the same names. Dfs now
|
|
retries when creating a file long enough for locks on abandoned
|
|
files to expire. (omalley via cutting)
|
|
|
|
22. Fix HADOOP-150. Improved task names that include job
|
|
names. (omalley via cutting)
|
|
|
|
23. Fix HADOOP-162. Fix ConcurrentModificationException when
|
|
releasing file locks. (omalley via cutting)
|
|
|
|
24. Fix HADOOP-132. Initial check-in of new Metrics API, including
|
|
implementations for writing metric data to a file and for sending
|
|
it to Ganglia. (David Bowen via cutting)
|
|
|
|
25. Fix HADOOP-160. Remove some uneeded synchronization around
|
|
time-consuming operations in the TaskTracker. (omalley via cutting)
|
|
|
|
26. Fix HADOOP-166. RPCs failed when passed subclasses of a declared
|
|
parameter type. This is fixed by changing ObjectWritable to store
|
|
both the declared type and the instance type for Writables. Note
|
|
that this incompatibly changes the format of ObjectWritable and
|
|
will render unreadable any ObjectWritables stored in files.
|
|
Nutch only uses ObjectWritable in intermediate files, so this
|
|
should not be a problem for Nutch. (Stefan & cutting)
|
|
|
|
27. Fix HADOOP-168. MapReduce RPC protocol methods should all declare
|
|
IOException, so that timeouts are handled appropriately.
|
|
(omalley via cutting)
|
|
|
|
28. Fix HADOOP-169. Don't fail a reduce task if a call to the
|
|
jobtracker to locate map outputs fails. (omalley via cutting)
|
|
|
|
29. Fix HADOOP-170. Permit FileSystem clients to examine and modify
|
|
the replication count of individual files. Also fix a few
|
|
replication-related bugs. (Konstantin Shvachko via cutting)
|
|
|
|
30. Permit specification of a higher replication levels for job
|
|
submission files (job.xml and job.jar). This helps with large
|
|
clusters, since these files are read by every node. (cutting)
|
|
|
|
31. HADOOP-173. Optimize allocation of tasks with local data. (cutting)
|
|
|
|
32. HADOOP-167. Reduce number of Configurations and JobConf's
|
|
created. (omalley via cutting)
|
|
|
|
33. NUTCH-256. Change FileSystem#createNewFile() to create a .crc
|
|
file. The lack of a .crc file was causing warnings. (cutting)
|
|
|
|
34. HADOOP-174. Change JobClient to not abort job until it has failed
|
|
to contact the job tracker for five attempts, not just one as
|
|
before. (omalley via cutting)
|
|
|
|
35. HADOOP-177. Change MapReduce web interface to page through tasks.
|
|
Previously, when jobs had more than a few thousand tasks they
|
|
could crash web browsers. (Mahadev Konar via cutting)
|
|
|
|
36. HADOOP-178. In DFS, piggyback blockwork requests from datanodes
|
|
on heartbeat responses from namenode. This reduces the volume of
|
|
RPC traffic. Also move startup delay in blockwork from datanode
|
|
to namenode. This fixes a problem where restarting the namenode
|
|
triggered a lot of uneeded replication. (Hairong Kuang via cutting)
|
|
|
|
37. HADOOP-183. If the DFS namenode is restarted with different
|
|
minimum and/or maximum replication counts, existing files'
|
|
replication counts are now automatically adjusted to be within the
|
|
newly configured bounds. (Hairong Kuang via cutting)
|
|
|
|
38. HADOOP-186. Better error handling in TaskTracker's top-level
|
|
loop. Also improve calculation of time to send next heartbeat.
|
|
(omalley via cutting)
|
|
|
|
39. HADOOP-187. Add two MapReduce examples/benchmarks. One creates
|
|
files containing random data. The second sorts the output of the
|
|
first. (omalley via cutting)
|
|
|
|
40. HADOOP-185. Fix so that, when a task tracker times out making the
|
|
RPC asking for a new task to run, the job tracker does not think
|
|
that it is actually running the task returned. (omalley via cutting)
|
|
|
|
41. HADOOP-190. If a child process hangs after it has reported
|
|
completion, its output should not be lost. (Stack via cutting)
|
|
|
|
42. HADOOP-184. Re-structure some test code to better support testing
|
|
on a cluster. (Mahadev Konar via cutting)
|
|
|
|
43. HADOOP-191 Add streaming package, Hadoop's first contrib module.
|
|
This permits folks to easily submit MapReduce jobs whose map and
|
|
reduce functions are implemented by shell commands. Use
|
|
'bin/hadoop jar build/hadoop-streaming.jar' to get details.
|
|
(Michel Tourn via cutting)
|
|
|
|
44. HADOOP-189. Fix MapReduce in standalone configuration to
|
|
correctly handle job jar files that contain a lib directory with
|
|
nested jar files. (cutting)
|
|
|
|
45. HADOOP-65. Initial version of record I/O framework that enables
|
|
the specification of record types and generates marshalling code
|
|
in both Java and C++. Generated Java code implements
|
|
WritableComparable, but is not yet otherwise used by
|
|
Hadoop. (Milind Bhandarkar via cutting)
|
|
|
|
46. HADOOP-193. Add a MapReduce-based FileSystem benchmark.
|
|
(Konstantin Shvachko via cutting)
|
|
|
|
47. HADOOP-194. Add a MapReduce-based FileSystem checker. This reads
|
|
every block in every file in the filesystem. (Konstantin Shvachko
|
|
via cutting)
|
|
|
|
48. HADOOP-182. Fix so that lost task trackers to not change the
|
|
status of reduce tasks or completed jobs. Also fixes the progress
|
|
meter so that failed tasks are subtracted. (omalley via cutting)
|
|
|
|
49. HADOOP-96. Logging improvements. Log files are now separate from
|
|
standard output and standard error files. Logs are now rolled.
|
|
Logging of all DFS state changes can be enabled, to facilitate
|
|
debugging. (Hairong Kuang via cutting)
|
|
|
|
|
|
Release 0.1.1 - 2006-04-08
|
|
|
|
1. Added CHANGES.txt, logging all significant changes to Hadoop. (cutting)
|
|
|
|
2. Fix MapReduceBase.close() to throw IOException, as declared in the
|
|
Closeable interface. This permits subclasses which override this
|
|
method to throw that exception. (cutting)
|
|
|
|
3. Fix HADOOP-117. Pathnames were mistakenly transposed in
|
|
JobConf.getLocalFile() causing many mapred temporary files to not
|
|
be removed. (Raghavendra Prabhu via cutting)
|
|
|
|
4. Fix HADOOP-116. Clean up job submission files when jobs complete.
|
|
(cutting)
|
|
|
|
5. Fix HADOOP-125. Fix handling of absolute paths on Windows (cutting)
|
|
|
|
Release 0.1.0 - 2006-04-01
|
|
|
|
1. The first release of Hadoop.
|
|
|
