||
access control. (Kan Zhang via cdouglas)

|
||
(szetszwo)
|

|
||
by Chukwa)
|
||
Added FileAdaptor for streaming small file in one chunk
|
||
Added compression to archive and demux output
|
||
Added unit tests and validation for agent, collector, and demux map
|
||
reduce job
|
||

|
||
connected database
|
||

|
||
populated key space (Andrzej Bialecki via stack)
|
||
|
||
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.
|
||

|
||
(Amareshwari Sriramadasu via ddas)
|
||
|
||
HADOOP-4688. Modify the MiniMRDFSSort unit test to spill multiple times,

HADOOP-4838. Added a registry to automate metrics and mbeans management.
|
||
(Sanjay Radia via acmurthy)
|
||
|
||
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.
|
||
Configuration changes to mapred-default.xml:
|
||
add mapred.reduce.slowstart.completed.maps
|

|
||
the Configured capacity
|
||
DFS Used % - DFS Used % of Configured Capacity
|
||
DFS Remaining % - Remaing % Configured Capacity available for DFS use

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)
|
||
|
||

|
||
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-3265. Removed depcrecated API getFileCacheHints().
|
||
(Lohit Vijayarenu via rangadi)

||
(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)

||
(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().
|
||

|
||
Release 0.15.1 - 2007-11-27

|
||
|
||

|
||
hadoop clusters.
|
||
* mapred_tutorial.html is a comprehensive Map-Reduce tutorial.

stored the value caused initialization problems.

||
(Raghu Angadi via cutting)
|
||
|

scheme and host. (tomwhite)
|
||
|

HADOOP-1695. The SecondaryNamenode waits for the Primary NameNode to
|
||
start up. (Dhruba Borthakur)
|
||
|
||
HADOOP-1983. Have Pipes flush the command socket when progress is sent
|
||
to prevent timeouts during long computations. (omalley)
|
||
|
||
HADOOP-1875. Non-existant directories or read-only directories are
|
||
filtered from dfs.client.buffer.dir. (Hairong Kuang via dhruba)
|
||
|
||
HADOOP-1992. Fix the performance degradation in the sort validator.
|
||
(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
|
||
recorded at the JobTracker, so that, for example, one may view correct
|
||
information via taskdetails.jsp. This bug was introduced by HADOOP-1874.
|
||
(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
|
||
properly i.e. the map TIP is incorrectly left marked as 'complete' and it
|
||
is never rescheduled elsewhere, leading to hung reduces.
|
||
(Devaraj Das via acmurthy)
|
||
|
||
HADOOP-2018. The source datanode of a data transfer waits for
|
||
a response from the target datanode before closing the data stream.
|
||
(Hairong Kuang via dhruba)
|
||
|
||
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
|
||
IOException in MROutputThread. (lohit vijayarenu via nigel)

specified and the destination does not need to exist.
|
||
(Chris Douglas via nigel)
|
||
|
||
HADOOP-2044. The namenode protects all lease manipulations using a
|
||
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
|
||
that before waiting for the application to finish to ensure all buffered
|
||
data is flushed. (Owen O'Malley via acmurthy)

||
HADOOP-2080. Fixed calculation of the checksum file size when the values
|
||
are large. (omalley)

|
||
as much as possible before reporting the error. Also report progress on
|
||
every copy. (Chris Douglas via omalley)
|
||
|
||
HADOOP-2073. Change size of VERSION file after writing contents to it.
|
||
(Konstantin Shvachko via dhruba)
|
||
|
||
HADOOP-2102. Fix the deprecated ToolBase to pass its Configuration object
|
||
to the superceding ToolRunner to ensure it picks up the appropriate
|
||
configuration resources. (Dennis Kubes and Enis Soztutar via acmurthy)
|
||
|
||
HADOOP-2103. Fix minor javadoc bugs introduce by HADOOP-2046. (Nigel
|
||
Daley via acmurthy)
|
||
|
||
IMPROVEMENTS

||
|
||
HADOOP-1921. Save the configuration of completed/failed jobs and make them

single lookup. This facilitates removal of the 'parent' field in the
|
||
inode. (Christophe Taton via dhruba)
|
||
|
||
HADOOP-1756. Add toString() to some Writable-s. (ab)

|

(cutting)
|
||
|

code in Hadoop so that you can copy from and to all of the supported file
|
||
systems.(Chris Douglas via omalley)

HADOOP-1018. Improve documentation w.r.t handling of lost hearbeats between

7. HADOOP-871. Fix a bug in bin/hadoop setting JAVA_LIBRARY_PATH.
|
||
(Arun C Murthy via cutting)

|
||
respecting io.sort.fa ctor. (Devaraj Das via cutting)
|
||
|

|
||
than the default, zlib-based compression, but it is only available
|
||
when the native library is built. (Arun C Murthy via cutting)
|

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

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

Release 0.10.0 - 2007-01-05
|
||
|
||
1. HADOOP-763. Change DFS namenode benchmark to not use MapReduce.
|
||
(Nigel Daley via cutting)
|
||
|
||
2. HADOOP-777. Use fully-qualified hostnames for tasktrackers and
|
||
datanodes. (Mahadev Konar via cutting)
|
||
|
||
3. HADOOP-621. Change 'dfs -cat' to exit sooner when output has been
|
||
closed. (Dhruba Borthakur via cutting)
|
||
|
||
4. HADOOP-752. Rationalize some synchronization in DFS namenode.
|
||
(Dhruba Borthakur via cutting)
|
||
|
||
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)
|
||
|
||
9. [Included in 0.9.2 release]
|

||
10. HADOOP-756. Add new dfsadmin option to wait for filesystem to be
|
||
operational. (Dhruba Borthakur via cutting)
|
||
|
||
11. HADOOP-770. Fix jobtracker web interface to display, on restart,
|
||
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)
|
||
|
||
14. HADOOP-786. Log common exception at debug level.
|
||
(Sanjay Dahiya via cutting)
|
||
|
||
15. HADOOP-796. Provide more convenient access to failed task
|
||
information in the web interface. (Sanjay Dahiya via cutting)
|
||
|
||
16. HADOOP-764. Reduce memory allocations in namenode some.
|
||
(Dhruba Borthakur via cutting)
|
||
|
||
17. HADOOP-802. Update description of mapred.speculative.execution to
|
||
mention reduces. (Nigel Daley via cutting)

|
||
21. HADOOP-792. Fix 'dfs -mv' to return correct status.
|
||
(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)
|
||
|
||
25. HADOOP-794. Fix a divide-by-zero exception when a job specifies
|
||
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.
|
||
(Devaraj Das via cutting)
|
||
|
||
30. HADOOP-825. Fix HDFS daemons when configured with new URI syntax.
|
||
(omalley via cutting)

||
32. HADOOP-811. Add a utility, MultithreadedMapRunner.
|
||
(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)
|
||
|
||
44. HADOOP-849. Fix OutOfMemory exceptions in TaskTracker due to a
|
||
file handle leak in SequenceFile. (Devaraj Das via cutting)

|
||
integers. (ab via cutting)

|
||
improves record sort performance. (Milind Bhandarkar via cutting)
|
||
|
||
48. HADOOP-628. Fix a problem with 'fs -cat' command, where some
|
||
characters were replaced with question marks. (Wendy Chien via cutting)
|
||
|
||
49. HADOOP-804. Reduce verbosity of MapReduce logging.
|
||
(Sanjay Dahiya via cutting)
|
||
|
||
50. HADOOP-853. Rename 'site' to 'docs', in preparation for inclusion
|
||
in releases. (cutting)
|
||
|
||
51. HADOOP-371. Include contrib jars and site documentation in
|
||
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
|
||
change contrib/streaming to use this. (Sanjay Dahia via cutting)
|
||
|
||
|
||
Release 0.9.2 - 2006-12-15
|
||

1. HADOOP-655. Remove most deprecated code. A few deprecated things
|
||
remain, notably UTF8 and some methods that are still required.
|
||
Also cleaned up constructors for SequenceFile, MapFile, SetFile,
|
||
and ArrayFile a bit. (cutting)
|
||
|
||
2. HADOOP-565. Upgrade to Jetty version 6. (Sanjay Dahiya via cutting)
|
||
|
||
3. HADOOP-682. Fix DFS format command to work correctly when
|
||
configured with a non-existent directory. (Sanjay Dahiya via cutting)
|

|
||
(Mahadev Konar via cutting)
|
||
|

||
are not collected like normal buffers, and provided little
|
||
advantage. (Raghu Angadi via cutting)
|
||
|
||
12. HADOOP-696. Fix TestTextInputFormat unit test to not rely on the
|
||
order of directory listings. (Sameer Paranjpye via cutting)

|
||
not completely cleaned up. (Mahadev Konar via cutting)
|
||
|
||
18. HADOOP-613. Perform final merge while reducing. This removes one
|
||
sort pass over the data and should consequently significantly
|

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

|
||
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)

|
||
paths. (Raghu Angadi via cutting)
|

31. HADOOP-733. Make exit codes in DFShell consistent and add a unit
|
||
test. (Dhruba Borthakur via cutting)
|

|
||
32. HADOOP-709. Fix contrib/streaming to work with commands that
|
||
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

37. HADOOP-739. Fix TestIPC to use different port number, making it
|
||
more reliable. (Nigel Daley via cutting)
|
||
|
||
38. HADOOP-749. Fix a NullPointerException in jobfailures.jsp.
|
||
(omalley via cutting)
|
||
|
||
39. HADOOP-747. Fix record serialization to work correctly when
|
||
records are embedded in Maps. (Milind Bhandarkar via cutting)
|
||
|
||
40. HADOOP-698. Fix HDFS client not to retry the same datanode on
|
||
read failures. (Milind Bhandarkar via cutting)
|
||
|
||
41. HADOOP-689. Add GenericWritable, to facilitate polymorphism in
|
||
MapReduce, SequenceFile, etc. (Feng Jiang via cutting)
|
||
|
||
42. HADOOP-430. Stop datanode's HTTP server when registration with
|
||
namenode fails. (Wendy Chien via cutting)
|
||
|
||
43. HADOOP-750. Fix a potential race condition during mapreduce
|
||
shuffle. (omalley via cutting)
|
||
|
||
44. HADOOP-728. Fix contrib/streaming-related issues, including
|
||
'-reducer NONE'. (Sanjay Dahiya via cutting)
|
||
|
||
|
||
Release 0.8.0 - 2006-11-03
|
||
|
||
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.
|
||
(omalley via cutting)
|
||
|
||
|
||
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)

|
||
(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)
|

|
||
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.
|

|
||
(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
|
||
|
||

|
||
/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)

|
||
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)

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)
|
||
|

|
||
(Milind Bhandarkar via cutting)
|
||
|
||

|
||
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

|
||
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.
