  4566. populated key space (Andrzej Bialecki via stack)
  4567. HADOOP-1230. Add new map/reduce API and deprecate the old one. Generally,
  4568. the old code should work without problem. The new api is in
  4569. org.apache.hadoop.mapreduce and the old classes in org.apache.hadoop.mapred
  4570. are deprecated. Differences in the new API:

  4572. methods without breaking compatability.
  4573. 2. Mapper and Reducer now have a "run" method that is called once and

  4575. replace it.
  4576. 3. Mapper and Reducer by default are Identity Mapper and Reducer.
  4577. 4. The FileOutputFormats use part-r-00000 for the output of reduce 0 and

  4606. to HttpServer. (Kan Zhang via cdouglas)
  4607. HADOOP-4276. Improve the hashing functions and deserialization of the
  4608. mapred ID classes. (omalley)

  4685. (Sanjay Radia via acmurthy)
  4686. HADOOP-3136. Fixed the default scheduler to assign multiple tasks to each
  4687. tasktracker per heartbeat, when feasible. To ensure locality isn't hurt
  4688. too badly, the scheudler will not assign more than one off-switch task per
  4689. heartbeat. The heartbeat interval is also halved since the task-tracker is
  4690. fixed to no longer send out heartbeats on each task completion. A
  4691. slow-start for scheduling reduces is introduced to ensure that reduces
  4692. aren't started till sufficient number of maps are done, else reduces of
  4693. jobs whose maps aren't scheduled might swamp the cluster.

  4723. files. (Rama Ramasamy via dhruba)
  4724. HADOOP-4804. Provide Forrest documentation for the Fair Scheduler.
  4725. (Sreekanth Ramakrishnan via yhemanth)
  4726. HADOOP-5248. A testcase that checks for the existence of job directory
  4727. after the job completes. Fails if it exists. (ddas)
  4728. HADOOP-4664. Introduces multiple job initialization threads, where the
  4729. number of threads are configurable via mapred.jobinit.threads.

  6069. the real block directory on a datanode-restart. (dhruba)
  6070. HADOOP-3452. Change fsck to return non-zero status for a corrupt

  7897. (Amar Kamat via acmurthy)
  7898. HADOOP-2031. Correctly maintain the taskid which takes the TIP to

  7902. (Devaraj Das via acmurthy)
  7903. HADOOP-2018. The source datanode of a data transfer waits for

  7922. HADOOP-1973. The FileSystem object would be accessed on the JobTracker
  7923. through a RPC in the InterTrackerProtocol. The check for the object being
  7924. null was missing and hence NPE would be thrown sometimes. This issue fixes
  7925. that problem. (Amareshwari Sri Ramadasu via ddas)
  7926. HADOOP-2033. The SequenceFile.Writer.sync method was a no-op, which caused
  7927. very uneven splits for applications like distcp that count on them.
  7928. (omalley)

  7960. (Devaraj Das via tomwhite)
  7961. HADOOP-1595. dfsshell can wait for a file to achieve its intended
  7962. replication target. (Tsz Wo (Nicholas), SZE via dhruba)
  7963. HADOOP-1693. Remove un-needed log fields in DFS replication classes,
  7964. since the log may be accessed statically. (Konstantin Shvachko via cutting)

  7966. (tomwhite via cutting)
  7967. HADOOP-1436. Improved command-line APIs, so that all tools need

  9061. datanodes in more circumstances. (Hairong Kuang via cutting)
  9062. 31. HADOOP-922. Optimize small forward seeks in HDFS. If data is has
  9063. likely already in flight, skip ahead rather than re-opening the

  9144. version. (omalley via cutting)
  9145. 6. HADOOP-774. Limit the number of invalid blocks returned with
  9146. heartbeats by the namenode to datanodes. Transmitting and
  9147. processing very large invalid block lists can tie up both the
  9148. namenode and datanode for too long. (Dhruba Borthakur via cutting)
  9149. 7. HADOOP-738. Change 'dfs -get' command to not create CRC files by
  9150. default, adding a -crc option to force their creation.

  9158. jobs that were running when it was last stopped.
  9159. (Sanjay Dahiya via cutting)
  9160. 12. HADOOP-331. Write all map outputs to a single file with an index,
  9161. rather than to a separate file per reduce task. This should both
  9162. speed the shuffle and make things more scalable.
  9163. (Devaraj Das via cutting)
  9164. 13. HADOOP-818. Fix contrib unit tests to not depend on core unit
  9165. tests. (omalley via cutting)

  9182. (Mahadev Konar via cutting)
  9183. 23. HADOOP-571. Extend the syntax of Path to be a URI; to be
  9184. optionally qualified with a scheme and authority. The scheme
  9185. determines the FileSystem implementation, while the authority
  9186. determines the FileSystem instance. New FileSystem
  9187. implementations may be provided by defining an fs.<scheme>.impl
  9188. property, naming the FileSystem implementation class. This
  9189. permits easy integration of new FileSystem implementations.
  9190. (cutting)
  9191. 24. HADOOP-720. Add an HDFS white paper to website.
  9192. (Dhruba Borthakur via cutting)

  9196. usage. (Hairong Kuang via cutting)
  9197. 27. HADOOP-574. Add an Amazon S3 implementation of FileSystem. To
  9198. use this, one need only specify paths of the form
  9199. s3://id:secret@bucket/. Alternately, the AWS access key id and
  9200. secret can be specified in your config, with the properties
  9201. fs.s3.awsAccessKeyId and fs.s3.awsSecretAccessKey.
  9202. (Tom White via cutting)
  9203. 28. HADOOP-824. Rename DFSShell to be FsShell, since it applies
  9204. generically to all FileSystem implementations. (cutting)
  9205. 29. HADOOP-813. Fix map output sorting to report progress, so that
  9206. sorts which take longer than the task timeout do not fail.
  9207. (Devaraj Das via cutting)
  9208. 30. HADOOP-825. Fix HDFS daemons when configured with new URI syntax.

  9217. (Dhruba Borthakur via cutting)
  9218. 34. HADOOP-823. Fix problem starting datanode when not all configured
  9219. data directories exist. (Bryan Pendleton via cutting)
  9220. 35. HADOOP-451. Add a Split interface. CAUTION: This incompatibly
  9221. changes the InputFormat and RecordReader interfaces. Not only is
  9222. FileSplit replaced with Split, but a FileSystem parameter is no
  9223. longer passed in several methods, input validation has changed,
  9224. etc. (omalley via cutting)
  9225. 36. HADOOP-814. Optimize locking in namenode. (Dhruba Borthakur via cutting)
  9226. 37. HADOOP-738. Change 'fs -put' and 'fs -get' commands to accept
  9227. standard input and output, respectively. Standard i/o is
  9228. specified by a file named '-'. (Wendy Chien via cutting)
  9229. 38. HADOOP-835. Fix a NullPointerException reading record-compressed
  9230. SequenceFiles. (Hairong Kuang via cutting)
  9231. 39. HADOOP-836. Fix a MapReduce bug on Windows, where the wrong
  9232. FileSystem was used. Also add a static FileSystem.getLocal()
  9233. method and better Path checking in HDFS, to help avoid such issues
  9234. in the future. (omalley via cutting)
  9235. 40. HADOOP-837. Improve RunJar utility to unpack jar file

  9263. intermediate outputs may happen at any time, potentially causing
  9264. task timeouts. (Devaraj Das via cutting)
  9265. 53. HADOOP-840. In task tracker, queue task cleanups and perform them
  9266. in a separate thread. (omalley & Mahadev Konar via cutting)
  9267. 54. HADOOP-681. Add to HDFS the ability to decommission nodes. This
  9268. causes their blocks to be re-replicated on other nodes, so that
  9269. they may be removed from a cluster. (Dhruba Borthakur via cutting)
  9270. 55. HADOOP-470. In HDFS web ui, list the datanodes containing each

  9362. contain control characters. (Dhruba Borthakur via cutting)
  9363. 33. HADOOP-677. In IPC, permit a version header to be transmitted
  9364. when connections are established. This will permit us to change
  9365. the format of IPC requests back-compatibly in subsequent releases.
  9366. (omalley via cutting)
  9367. 34. HADOOP-699. Fix DFS web interface so that filesystem browsing
  9368. works correctly, using the right port number. Also add support
  9369. for sorting datanode list by various columns.
  9370. (Raghu Angadi via cutting)
  9371. 35. HADOOP-76. Implement speculative reduce. Now when a job is
  9372. configured for speculative execution, both maps and reduces will
  9373. execute speculatively. Reduce outputs are written to temporary
  9374. location and moved to the final location when reduce is complete.
  9375. (Sanjay Dahiya via cutting)
  9376. 36. HADOOP-736. Roll back to Jetty 5.1.4, due to performance problems
  9377. with Jetty 6.0.1.
  9378. 37. HADOOP-739. Fix TestIPC to use different port number, making it
  9379. more reliable. (Nigel Daley via cutting)
  9380. 38. HADOOP-749. Fix a NullPointerException in jobfailures.jsp.
  9381. (omalley via cutting)
  9382. 39. HADOOP-747. Fix record serialization to work correctly when
  9383. records are embedded in Maps. (Milind Bhandarkar via cutting)
  9384. 40. HADOOP-698. Fix HDFS client not to retry the same datanode on
  9385. read failures. (Milind Bhandarkar via cutting)
  9386. 41. HADOOP-689. Add GenericWritable, to facilitate polymorphism in
  9387. MapReduce, SequenceFile, etc. (Feng Jiang via cutting)
  9388. 42. HADOOP-430. Stop datanode's HTTP server when registration with
  9389. namenode fails. (Wendy Chien via cutting)
  9390. 43. HADOOP-750. Fix a potential race condition during mapreduce
  9391. shuffle. (omalley via cutting)
  9392. 44. HADOOP-728. Fix contrib/streaming-related issues, including
  9393. '-reducer NONE'. (Sanjay Dahiya via cutting)
  9394. Release 0.8.0 - 2006-11-03
  9395. 1. HADOOP-477. Extend contrib/streaming to scan the PATH environment
  9396. variables when resolving executable program names.
  9397. (Dhruba Borthakur via cutting)
  9398. 2. HADOOP-583. In DFSClient, reduce the log level of re-connect
  9399. attempts from 'info' to 'debug', so they are not normally shown.
  9400. (Konstantin Shvachko via cutting)
  9401. 3. HADOOP-498. Re-implement DFS integrity checker to run server-side,
  9402. for much improved performance. (Milind Bhandarkar via cutting)
  9403. 4. HADOOP-586. Use the jar name for otherwise un-named jobs.
  9404. (Sanjay Dahiya via cutting)
  9405. 5. HADOOP-514. Make DFS heartbeat interval configurable.
  9406. (Milind Bhandarkar via cutting)
  9407. 6. HADOOP-588. Fix logging and accounting of failed tasks.
  9408. (Sanjay Dahiya via cutting)
  9409. 7. HADOOP-462. Improve command line parsing in DFSShell, so that
  9410. incorrect numbers of arguments result in informative errors rather
  9411. than ArrayOutOfBoundsException. (Dhruba Borthakur via cutting)
  9412. 8. HADOOP-561. Fix DFS so that one replica of each block is written
  9413. locally, if possible. This was the intent, but there as a bug.
  9414. (Dhruba Borthakur via cutting)
  9415. 9. HADOOP-610. Fix TaskTracker to survive more exceptions, keeping
  9416. tasks from becoming lost. (omalley via cutting)
  9417. 10. HADOOP-625. Add a servlet to all http daemons that displays a
  9418. stack dump, useful for debugging. (omalley via cutting)
  9419. 11. HADOOP-554. Fix DFSShell to return -1 for errors.
  9420. (Dhruba Borthakur via cutting)
  9421. 12. HADOOP-626. Correct the documentation in the NNBench example
  9422. code, and also remove a mistaken call there.
  9423. (Nigel Daley via cutting)
  9424. 13. HADOOP-634. Add missing license to many files.
  9425. (Nigel Daley via cutting)
  9426. 14. HADOOP-627. Fix some synchronization problems in MiniMRCluster
  9427. that sometimes caused unit tests to fail. (Nigel Daley via cutting)
  9428. 15. HADOOP-563. Improve the NameNode's lease policy so that leases
  9429. are held for one hour without renewal (instead of one minute).
  9430. However another attempt to create the same file will still succeed
  9431. if the lease has not been renewed within a minute. This prevents
  9432. communication or scheduling problems from causing a write to fail
  9433. for up to an hour, barring some other process trying to create the
  9434. same file. (Dhruba Borthakur via cutting)
  9435. 16. HADOOP-635. In DFSShell, permit specification of multiple files
  9436. as the source for file copy and move commands.
  9437. (Dhruba Borthakur via cutting)
  9438. 17. HADOOP-641. Change NameNode to request a fresh block report from
  9439. a re-discovered DataNode, so that no-longer-needed replications
  9440. are stopped promptly. (Konstantin Shvachko via cutting)
  9441. 18. HADOOP-642. Change IPC client to specify an explicit connect
  9442. timeout. (Konstantin Shvachko via cutting)
  9443. 19. HADOOP-638. Fix an unsynchronized access to TaskTracker's
  9444. internal state. (Nigel Daley via cutting)
  9445. 20. HADOOP-624. Fix servlet path to stop a Jetty warning on startup.
  9446. (omalley via cutting)
  9447. 21. HADOOP-578. Failed tasks are no longer placed at the end of the
  9448. task queue. This was originally done to work around other
  9449. problems that have now been fixed. Re-executing failed tasks
  9450. sooner causes buggy jobs to fail faster. (Sanjay Dahiya via cutting)
  9451. 22. HADOOP-658. Update source file headers per Apache policy. (cutting)
  9452. 23. HADOOP-636. Add MapFile & ArrayFile constructors which accept a
  9453. Progressable, and pass it down to SequenceFile. This permits
  9454. reduce tasks which use MapFile to still report progress while
  9455. writing blocks to the filesystem. (cutting)
  9456. 24. HADOOP-576. Enable contrib/streaming to use the file cache. Also
  9457. extend the cache to permit symbolic links to cached items, rather
  9458. than local file copies. (Mahadev Konar via cutting)
  9459. 25. HADOOP-482. Fix unit tests to work when a cluster is running on
  9460. the same machine, removing port conflicts. (Wendy Chien via cutting)
  9461. 26. HADOOP-90. Permit dfs.name.dir to list multiple directories,
  9462. where namenode data is to be replicated. (Milind Bhandarkar via cutting)
  9463. 27. HADOOP-651. Fix DFSCk to correctly pass parameters to the servlet
  9464. on the namenode. (Milind Bhandarkar via cutting)
  9465. 28. HADOOP-553. Change main() routines of DataNode and NameNode to
  9466. log exceptions rather than letting the JVM print them to standard
  9467. error. Also, change the hadoop-daemon.sh script to rotate
  9468. standard i/o log files. (Raghu Angadi via cutting)
  9469. 29. HADOOP-399. Fix javadoc warnings. (Nigel Daley via cutting)
  9470. 30. HADOOP-599. Fix web ui and command line to correctly report DFS
  9471. filesystem size statistics. Also improve web layout.
  9472. (Raghu Angadi via cutting)
  9473. 31. HADOOP-660. Permit specification of junit test output format.
  9474. (Nigel Daley via cutting)
  9475. 32. HADOOP-663. Fix a few unit test issues. (Mahadev Konar via cutting)
  9476. 33. HADOOP-664. Cause entire build to fail if libhdfs tests fail.
  9477. (Nigel Daley via cutting)
  9478. 34. HADOOP-633. Keep jobtracker from dying when job initialization
  9479. throws exceptions. Also improve exception handling in a few other
  9480. places and add more informative thread names.
  9481. (omalley via cutting)
  9482. 35. HADOOP-669. Fix a problem introduced by HADOOP-90 that can cause
  9483. DFS to lose files. (Milind Bhandarkar via cutting)
  9484. 36. HADOOP-373. Consistently check the value returned by
  9485. FileSystem.mkdirs(). (Wendy Chien via cutting)
  9486. 37. HADOOP-670. Code cleanups in some DFS internals: use generic
  9487. types, replace Vector with ArrayList, etc.
  9488. (Konstantin Shvachko via cutting)
  9489. 38. HADOOP-647. Permit map outputs to use a different compression
  9490. type than the job output. (omalley via cutting)
  9491. 39. HADOOP-671. Fix file cache to check for pre-existence before
  9492. creating . (Mahadev Konar via cutting)
  9493. 40. HADOOP-665. Extend many DFSShell commands to accept multiple
  9494. arguments. Now commands like "ls", "rm", etc. will operate on
  9495. multiple files. (Dhruba Borthakur via cutting)
  9496. Release 0.7.2 - 2006-10-18
  9497. 1. HADOOP-607. Fix a bug where classes included in job jars were not
  9498. found by tasks. (Mahadev Konar via cutting)
  9499. 2. HADOOP-609. Add a unit test that checks that classes in job jars
  9500. can be found by tasks. Also modify unit tests to specify multiple
  9501. local directories. (Mahadev Konar via cutting)
  9502. Release 0.7.1 - 2006-10-11
  9503. 1. HADOOP-593. Fix a NullPointerException in the JobTracker.
  9504. (omalley via cutting)
  9505. 2. HADOOP-592. Fix a NullPointerException in the IPC Server. Also
  9506. consistently log when stale calls are discarded. (omalley via cutting)
  9507. 3. HADOOP-594. Increase the DFS safe-mode threshold from .95 to
  9508. .999, so that nearly all blocks must be reported before filesystem
  9509. modifications are permitted. (Konstantin Shvachko via cutting)
  9510. 4. HADOOP-598. Fix tasks to retry when reporting completion, so that
  9511. a single RPC timeout won't fail a task. (omalley via cutting)
  9512. 5. HADOOP-597. Fix TaskTracker to not discard map outputs for errors
  9513. in transmitting them to reduce nodes. (omalley via cutting)
  9514. Release 0.7.0 - 2006-10-06
  9515. 1. HADOOP-243. Fix rounding in the display of task and job progress
  9516. so that things are not shown to be 100% complete until they are in
  9517. fact finished. (omalley via cutting)
  9518. 2. HADOOP-438. Limit the length of absolute paths in DFS, since the
  9519. file format used to store pathnames has some limitations.
  9520. (Wendy Chien via cutting)
  9521. 3. HADOOP-530. Improve error messages in SequenceFile when keys or
  9522. values are of the wrong type. (Hairong Kuang via cutting)
  9523. 4. HADOOP-288. Add a file caching system and use it in MapReduce to
  9524. cache job jar files on slave nodes. (Mahadev Konar via cutting)
  9525. 5. HADOOP-533. Fix unit test to not modify conf directory.
  9526. (Hairong Kuang via cutting)
  9527. 6. HADOOP-527. Permit specification of the local address that various
  9528. Hadoop daemons should bind to. (Philippe Gassmann via cutting)
  9529. 7. HADOOP-542. Updates to contrib/streaming: reformatted source code,
  9530. on-the-fly merge sort, a fix for HADOOP-540, etc.
  9531. (Michel Tourn via cutting)
  9532. 8. HADOOP-545. Remove an unused config file parameter.
  9533. (Philippe Gassmann via cutting)
  9534. 9. HADOOP-548. Add an Ant property "test.output" to build.xml that
  9535. causes test output to be logged to the console. (omalley via cutting)
  9536. 10. HADOOP-261. Record an error message when map output is lost.
  9537. (omalley via cutting)
  9538. 11. HADOOP-293. Report the full list of task error messages in the
  9539. web ui, not just the most recent. (omalley via cutting)
  9540. 12. HADOOP-551. Restore JobClient's console printouts to only include
  9541. a maximum of one update per one percent of progress.
  9542. (omalley via cutting)
  9543. 13. HADOOP-306. Add a "safe" mode to DFS. The name node enters this
  9544. when less than a specified percentage of file data is complete.
  9545. Currently safe mode is only used on startup, but eventually it
  9546. will also be entered when datanodes disconnect and file data
  9547. becomes incomplete. While in safe mode no filesystem
  9548. modifications are permitted and block replication is inhibited.
  9549. (Konstantin Shvachko via cutting)
  9550. 14. HADOOP-431. Change 'dfs -rm' to not operate recursively and add a
  9551. new command, 'dfs -rmr' which operates recursively.
  9552. (Sameer Paranjpye via cutting)
  9553. 15. HADOOP-263. Include timestamps for job transitions. The web
  9554. interface now displays the start and end times of tasks and the
  9555. start times of sorting and reducing for reduce tasks. Also,
  9556. extend ObjectWritable to handle enums, so that they can be passed
  9557. as RPC parameters. (Sanjay Dahiya via cutting)
  9558. 16. HADOOP-556. Contrib/streaming: send keep-alive reports to task
  9559. tracker every 10 seconds rather than every 100 records, to avoid
  9560. task timeouts. (Michel Tourn via cutting)
  9561. 17. HADOOP-547. Fix reduce tasks to ping tasktracker while copying
  9562. data, rather than only between copies, avoiding task timeouts.
  9563. (Sanjay Dahiya via cutting)
  9564. 18. HADOOP-537. Fix src/c++/libhdfs build process to create files in
  9565. build/, no longer modifying the source tree.
  9566. (Arun C Murthy via cutting)
  9567. 19. HADOOP-487. Throw a more informative exception for unknown RPC
  9568. hosts. (Sameer Paranjpye via cutting)
  9569. 20. HADOOP-559. Add file name globbing (pattern matching) support to
  9570. the FileSystem API, and use it in DFSShell ('bin/hadoop dfs')
  9571. commands. (Hairong Kuang via cutting)
  9572. 21. HADOOP-508. Fix a bug in FSDataInputStream. Incorrect data was
  9573. returned after seeking to a random location.
  9574. (Milind Bhandarkar via cutting)
  9575. 22. HADOOP-560. Add a "killed" task state. This can be used to
  9576. distinguish kills from other failures. Task state has also been
  9577. converted to use an enum type instead of an int, uncovering a bug
  9578. elsewhere. The web interface is also updated to display killed
  9579. tasks. (omalley via cutting)
  9580. 23. HADOOP-423. Normalize Paths containing directories named "." and
  9581. "..", using the standard, unix interpretation. Also add checks in
  9582. DFS, prohibiting the use of "." or ".." as directory or file
  9583. names. (Wendy Chien via cutting)
  9584. 24. HADOOP-513. Replace map output handling with a servlet, rather
  9585. than a JSP page. This fixes an issue where
  9586. IllegalStateException's were logged, sets content-length
  9587. correctly, and better handles some errors. (omalley via cutting)
  9588. 25. HADOOP-552. Improved error checking when copying map output files
  9589. to reduce nodes. (omalley via cutting)
  9590. 26. HADOOP-566. Fix scripts to work correctly when accessed through
  9591. relative symbolic links. (Lee Faris via cutting)
  9592. 27. HADOOP-519. Add positioned read methods to FSInputStream. These
  9593. permit one to read from a stream without moving its position, and
  9594. can hence be performed by multiple threads at once on a single
  9595. stream. Implement an optimized version for DFS and local FS.
  9596. (Milind Bhandarkar via cutting)
  9597. 28. HADOOP-522. Permit block compression with MapFile and SetFile.
  9598. Since these formats are always sorted, block compression can
  9599. provide a big advantage. (cutting)
  9600. 29. HADOOP-567. Record version and revision information in builds. A
  9601. package manifest is added to the generated jar file containing
  9602. version information, and a VersionInfo utility is added that
  9603. includes further information, including the build date and user,
  9604. and the subversion revision and repository. A 'bin/hadoop
  9605. version' comand is added to show this information, and it is also
  9606. added to various web interfaces. (omalley via cutting)
  9607. 30. HADOOP-568. Fix so that errors while initializing tasks on a
  9608. tasktracker correctly report the task as failed to the jobtracker,
  9609. so that it will be rescheduled. (omalley via cutting)
  9610. 31. HADOOP-550. Disable automatic UTF-8 validation in Text. This
  9611. permits, e.g., TextInputFormat to again operate on non-UTF-8 data.
  9612. (Hairong and Mahadev via cutting)
  9613. 32. HADOOP-343. Fix mapred copying so that a failed tasktracker
  9614. doesn't cause other copies to slow. (Sameer Paranjpye via cutting)
  9615. 33. HADOOP-239. Add a persistent job history mechanism, so that basic
  9616. job statistics are not lost after 24 hours and/or when the
  9617. jobtracker is restarted. (Sanjay Dahiya via cutting)
  9618. 34. HADOOP-506. Ignore heartbeats from stale task trackers.
  9619. (Sanjay Dahiya via cutting)
  9620. 35. HADOOP-255. Discard stale, queued IPC calls. Do not process
  9621. calls whose clients will likely time out before they receive a
  9622. response. When the queue is full, new calls are now received and
  9623. queued, and the oldest calls are discarded, so that, when servers
  9624. get bogged down, they no longer develop a backlog on the socket.
  9625. This should improve some DFS namenode failure modes.
  9626. (omalley via cutting)
  9627. 36. HADOOP-581. Fix datanode to not reset itself on communications
  9628. errors with the namenode. If a request to the namenode fails, the
  9629. datanode should retry, not restart. This reduces the load on the
  9630. namenode, since restarts cause a resend of the block report.
  9631. (omalley via cutting)
  9632. Release 0.6.2 - 2006-09-18
  9633. 1. HADOOP-532. Fix a bug reading value-compressed sequence files,
  9634. where an exception was thrown reporting that the full value had not
  9635. been read. (omalley via cutting)
  9636. 2. HADOOP-534. Change the default value class in JobConf to be Text
  9637. instead of the now-deprecated UTF8. This fixes the Grep example
  9638. program, which was updated to use Text, but relies on this
  9639. default. (Hairong Kuang via cutting)
  9640. Release 0.6.1 - 2006-09-13
  9641. 1. HADOOP-520. Fix a bug in libhdfs, where write failures were not
  9642. correctly returning error codes. (Arun C Murthy via cutting)
  9643. 2. HADOOP-523. Fix a NullPointerException when TextInputFormat is
  9644. explicitly specified. Also add a test case for this.
  9645. (omalley via cutting)
  9646. 3. HADOOP-521. Fix another NullPointerException finding the
  9647. ClassLoader when using libhdfs. (omalley via cutting)
  9648. 4. HADOOP-526. Fix a NullPointerException when attempting to start
  9649. two datanodes in the same directory. (Milind Bhandarkar via cutting)
  9650. 5. HADOOP-529. Fix a NullPointerException when opening
  9651. value-compressed sequence files generated by pre-0.6.0 Hadoop.
  9652. (omalley via cutting)
  9653. Release 0.6.0 - 2006-09-08
  9654. 1. HADOOP-427. Replace some uses of DatanodeDescriptor in the DFS
  9655. web UI code with DatanodeInfo, the preferred public class.
  9656. (Devaraj Das via cutting)
  9657. 2. HADOOP-426. Fix streaming contrib module to work correctly on
  9658. Solaris. This was causing nightly builds to fail.
  9659. (Michel Tourn via cutting)
  9660. 3. HADOOP-400. Improvements to task assignment. Tasks are no longer
  9661. re-run on nodes where they have failed (unless no other node is
  9662. available). Also, tasks are better load-balanced among nodes.
  9663. (omalley via cutting)
  9664. 4. HADOOP-324. Fix datanode to not exit when a disk is full, but
  9665. rather simply to fail writes. (Wendy Chien via cutting)
  9666. 5. HADOOP-434. Change smallJobsBenchmark to use standard Hadoop
  9667. scripts. (Sanjay Dahiya via cutting)
  9668. 6. HADOOP-453. Fix a bug in Text.setCapacity(). (siren via cutting)
  9669. 7. HADOOP-450. Change so that input types are determined by the
  9670. RecordReader rather than specified directly in the JobConf. This
  9671. facilitates jobs with a variety of input types.
  9672. WARNING: This contains incompatible API changes! The RecordReader
  9673. interface has two new methods that all user-defined InputFormats
  9674. must now define. Also, the values returned by TextInputFormat are
  9675. no longer of class UTF8, but now of class Text.
  9676. 8. HADOOP-436. Fix an error-handling bug in the web ui.
  9677. (Devaraj Das via cutting)
  9678. 9. HADOOP-455. Fix a bug in Text, where DEL was not permitted.
  9679. (Hairong Kuang via cutting)
  9680. 10. HADOOP-456. Change the DFS namenode to keep a persistent record
  9681. of the set of known datanodes. This will be used to implement a
  9682. "safe mode" where filesystem changes are prohibited when a
  9683. critical percentage of the datanodes are unavailable.
  9684. (Konstantin Shvachko via cutting)
  9685. 11. HADOOP-322. Add a job control utility. This permits one to
  9686. specify job interdependencies. Each job is submitted only after
  9687. the jobs it depends on have successfully completed.
  9688. (Runping Qi via cutting)
  9689. 12. HADOOP-176. Fix a bug in IntWritable.Comparator.
  9690. (Dick King via cutting)
  9691. 13. HADOOP-421. Replace uses of String in recordio package with Text
  9692. class, for improved handling of UTF-8 data.
  9693. (Milind Bhandarkar via cutting)
  9694. 14. HADOOP-464. Improved error message when job jar not found.
  9695. (Michel Tourn via cutting)
  9696. 15. HADOOP-469. Fix /bin/bash specifics that have crept into our
  9697. /bin/sh scripts since HADOOP-352.
  9698. (Jean-Baptiste Quenot via cutting)
  9699. 16. HADOOP-468. Add HADOOP_NICENESS environment variable to set
  9700. scheduling priority for daemons. (Vetle Roeim via cutting)
  9701. 17. HADOOP-473. Fix TextInputFormat to correctly handle more EOL
  9702. formats. Things now work correctly with CR, LF or CRLF.
  9703. (Dennis Kubes & James White via cutting)
  9704. 18. HADOOP-461. Make Java 1.5 an explicit requirement. (cutting)
  9705. 19. HADOOP-54. Add block compression to SequenceFile. One may now
  9706. specify that blocks of keys and values are compressed together,
  9707. improving compression for small keys and values.
  9708. SequenceFile.Writer's constructor is now deprecated and replaced
  9709. with a factory method. (Arun C Murthy via cutting)
  9710. 20. HADOOP-281. Prohibit DFS files that are also directories.
  9711. (Wendy Chien via cutting)
  9712. 21. HADOOP-486. Add the job username to JobStatus instances returned
  9713. by JobClient. (Mahadev Konar via cutting)
  9714. 22. HADOOP-437. contrib/streaming: Add support for gzipped inputs.
  9715. (Michel Tourn via cutting)
  9716. 23. HADOOP-463. Add variable expansion to config files.
  9717. Configuration property values may now contain variable
  9718. expressions. A variable is referenced with the syntax
  9719. '${variable}'. Variables values are found first in the
  9720. configuration, and then in Java system properties. The default
  9721. configuration is modified so that temporary directories are now
  9722. under ${hadoop.tmp.dir}, which is, by default,
  9723. /tmp/hadoop-${user.name}. (Michel Tourn via cutting)
  9724. 24. HADOOP-419. Fix a NullPointerException finding the ClassLoader
  9725. when using libhdfs. (omalley via cutting)

  9731. (Thomas Friol via cutting)
  9732. 28. HADOOP-499. Reduce the use of Strings in contrib/streaming,
  9733. replacing them with Text for better performance.
  9734. (Hairong Kuang via cutting)
  9735. 29. HADOOP-64. Manage multiple volumes with a single DataNode.
  9736. Previously DataNode would create a separate daemon per configured
  9737. volume, each with its own connection to the NameNode. Now all
  9738. volumes are handled by a single DataNode daemon, reducing the load
  9739. on the NameNode. (Milind Bhandarkar via cutting)
  9740. 30. HADOOP-424. Fix MapReduce so that jobs which generate zero splits
  9741. do not fail. (Fr??d??ric Bertin via cutting)
  9742. 31. HADOOP-408. Adjust some timeouts and remove some others so that

  9750. renewLease() calls when no files are being written.
  9751. (Konstantin Shvachko via cutting)
  9752. 35. HADOOP-312. Close idle IPC connections. All IPC connections were
  9753. cached forever. Now, after a connection has been idle for more
  9754. than a configurable amount of time (one second by default), the
  9755. connection is closed, conserving resources on both client and
  9756. server. (Devaraj Das via cutting)
  9757. 36. HADOOP-497. Permit the specification of the network interface and
  9758. nameserver to be used when determining the local hostname
  9759. advertised by datanodes and tasktrackers.
  9760. (Lorenzo Thione via cutting)
  9761. 37. HADOOP-441. Add a compression codec API and extend SequenceFile
  9762. to use it. This will permit the use of alternate compression
  9763. codecs in SequenceFile. (Arun C Murthy via cutting)
  9764. 38. HADOOP-483. Improvements to libhdfs build and documentation.
  9765. (Arun C Murthy via cutting)

  9769. (Hairong Kuang via cutting)
  9770. 41. HADOOP-474. Add CompressionCodecFactory, and use it in
  9771. TextInputFormat and TextOutputFormat. Compressed input files are
  9772. automatically decompressed when they have the correct extension.
  9773. Output files will, when output compression is specified, be
  9774. generated with an approprate extension. Also add a gzip codec and
  9775. fix problems with UTF8 text inputs. (omalley via cutting)
  9776. Release 0.5.0 - 2006-08-04
  9777. 1. HADOOP-352. Fix shell scripts to use /bin/sh instead of
  9778. /bin/bash, for better portability.
  9779. (Jean-Baptiste Quenot via cutting)
  9780. 2. HADOOP-313. Permit task state to be saved so that single tasks
  9781. may be manually re-executed when debugging. (omalley via cutting)
  9782. 3. HADOOP-339. Add method to JobClient API listing jobs that are
  9783. not yet complete, i.e., that are queued or running.
  9784. (Mahadev Konar via cutting)
  9785. 4. HADOOP-355. Updates to the streaming contrib module, including
  9786. API fixes, making reduce optional, and adding an input type for
  9787. StreamSequenceRecordReader. (Michel Tourn via cutting)

  9792. 7. HADOOP-359. Permit map output to be compressed.
  9793. (omalley via cutting)
  9794. 8. HADOOP-341. Permit input URI to CopyFiles to use the HTTP
  9795. protocol. This lets one, e.g., more easily copy log files into
  9796. DFS. (Arun C Murthy via cutting)
  9797. 9. HADOOP-361. Remove unix dependencies from streaming contrib
  9798. module tests, making them pure java. (Michel Tourn via cutting)
  9799. 10. HADOOP-354. Make public methods to stop DFS daemons.
  9800. (Barry Kaplan via cutting)
  9801. 11. HADOOP-252. Add versioning to RPC protocols.
  9802. (Milind Bhandarkar via cutting)
  9803. 12. HADOOP-356. Add contrib to "compile" and "test" build targets, so
  9804. that this code is better maintained. (Michel Tourn via cutting)
  9805. 13. HADOOP-307. Add smallJobsBenchmark contrib module. This runs
  9806. lots of small jobs, in order to determine per-task overheads.
  9807. (Sanjay Dahiya via cutting)
  9808. 14. HADOOP-342. Add a tool for log analysis: Logalyzer.
  9809. (Arun C Murthy via cutting)
  9810. 15. HADOOP-347. Add web-based browsing of DFS content. The namenode
  9811. redirects browsing requests to datanodes. Content requests are
  9812. redirected to datanodes where the data is local when possible.
  9813. (Devaraj Das via cutting)
  9814. 16. HADOOP-351. Make Hadoop IPC kernel independent of Jetty.
  9815. (Devaraj Das via cutting)
  9816. 17. HADOOP-237. Add metric reporting to DFS and MapReduce. With only
  9817. minor configuration changes, one can now monitor many Hadoop
  9818. system statistics using Ganglia or other monitoring systems.
  9819. (Milind Bhandarkar via cutting)
  9820. 18. HADOOP-376. Fix datanode's HTTP server to scan for a free port.

  9832. HADOOP-306. (Konstantin Shvachko & omalley via cutting)
  9833. 24. HADOOP-385. Fix some bugs in record io code generation.
  9834. (Milind Bhandarkar via cutting)
  9835. 25. HADOOP-302. Add new Text class to replace UTF8, removing

  9837. writing zero-compressed integers (VInts and VLongs).
  9838. (Hairong Kuang via cutting)
  9839. 26. HADOOP-335. Refactor DFS namespace/transaction logging in
  9840. namenode. (Konstantin Shvachko via cutting)
  9841. 27. HADOOP-375. Fix handling of the datanode HTTP daemon's port so
  9842. that multiple datanode's can be run on a single host.
  9843. (Devaraj Das via cutting)
  9844. 28. HADOOP-386. When removing excess DFS block replicas, remove those
  9845. on nodes with the least free space first.
  9846. (Johan Oskarson via cutting)
  9847. 29. HADOOP-389. Fix intermittent failures of mapreduce unit tests.

  9858. 34. HADOOP-345. Permit iteration over Configuration key/value pairs.
  9859. (Michel Tourn via cutting)
  9860. 35. HADOOP-409. Streaming contrib module: make configuration
  9861. properties available to commands as environment variables.
  9862. (Michel Tourn via cutting)
  9863. 36. HADOOP-369. Add -getmerge option to dfs command that appends all
  9864. files in a directory into a single local file.
  9865. (Johan Oskarson via cutting)
  9866. 37. HADOOP-410. Replace some TreeMaps with HashMaps in DFS, for
  9867. a 17% performance improvement. (Milind Bhandarkar via cutting)
  9868. 38. HADOOP-411. Add unit tests for command line parser.
  9869. (Hairong Kuang via cutting)

  9872. Also, move JobConf.newInstance() to a new utility class.
  9873. (Hairong Kuang via cutting)
  9874. 40. HADOOP-226. Fix fsck command to properly consider replication
  9875. counts, now that these can vary per file. (Bryan Pendleton via cutting)
  9876. 41. HADOOP-425. Add a Python MapReduce example, using Jython.
  9877. (omalley via cutting)
  9878. Release 0.4.0 - 2006-06-28
  9879. 1. HADOOP-298. Improved progress reports for CopyFiles utility, the
  9880. distributed file copier. (omalley via cutting)
  9881. 2. HADOOP-299. Fix the task tracker, permitting multiple jobs to
  9882. more easily execute at the same time. (omalley via cutting)
  9883. 3. HADOOP-250. Add an HTTP user interface to the namenode, running
  9884. on port 50070. (Devaraj Das via cutting)
  9885. 4. HADOOP-123. Add MapReduce unit tests that run a jobtracker and
  9886. tasktracker, greatly increasing code coverage.
  9887. (Milind Bhandarkar via cutting)
  9888. 5. HADOOP-271. Add links from jobtracker's web ui to tasktracker's
  9889. web ui. Also attempt to log a thread dump of child processes
  9890. before they're killed. (omalley via cutting)
  9891. 6. HADOOP-210. Change RPC server to use a selector instead of a
  9892. thread per connection. This should make it easier to scale to
  9893. larger clusters. Note that this incompatibly changes the RPC
  9894. protocol: clients and servers must both be upgraded to the new
  9895. version to ensure correct operation. (Devaraj Das via cutting)
  9896. 7. HADOOP-311. Change DFS client to retry failed reads, so that a
  9897. single read failure will not alone cause failure of a task.
  9898. (omalley via cutting)
  9899. 8. HADOOP-314. Remove the "append" phase when reducing. Map output
  9900. files are now directly passed to the sorter, without first
  9901. appending them into a single file. Now, the first third of reduce
  9902. progress is "copy" (transferring map output to reduce nodes), the
  9903. middle third is "sort" (sorting map output) and the last third is
  9904. "reduce" (generating output). Long-term, the "sort" phase will
  9905. also be removed. (omalley via cutting)
  9906. 9. HADOOP-316. Fix a potential deadlock in the jobtracker.
  9907. (omalley via cutting)
  9908. 10. HADOOP-319. Fix FileSystem.close() to remove the FileSystem
  9909. instance from the cache. (Hairong Kuang via cutting)
  9910. 11. HADOOP-135. Fix potential deadlock in JobTracker by acquiring
  9911. locks in a consistent order. (omalley via cutting)
  9912. 12. HADOOP-278. Check for existence of input directories before
  9913. starting MapReduce jobs, making it easier to debug this common
  9914. error. (omalley via cutting)
  9915. 13. HADOOP-304. Improve error message for
  9916. UnregisterdDatanodeException to include expected node name.
  9917. (Konstantin Shvachko via cutting)
  9918. 14. HADOOP-305. Fix TaskTracker to ask for new tasks as soon as a
  9919. task is finished, rather than waiting for the next heartbeat.
  9920. This improves performance when tasks are short.
  9921. (Mahadev Konar via cutting)
  9922. 15. HADOOP-59. Add support for generic command line options. One may
  9923. now specify the filesystem (-fs), the MapReduce jobtracker (-jt),
  9924. a config file (-conf) or any configuration property (-D). The
  9925. "dfs", "fsck", "job", and "distcp" commands currently support
  9926. this, with more to be added. (Hairong Kuang via cutting)
  9927. 16. HADOOP-296. Permit specification of the amount of reserved space
  9928. on a DFS datanode. One may specify both the percentage free and
  9929. the number of bytes. (Johan Oskarson via cutting)
  9930. 17. HADOOP-325. Fix a problem initializing RPC parameter classes, and
  9931. remove the workaround used to initialize classes.
  9932. (omalley via cutting)
  9933. 18. HADOOP-328. Add an option to the "distcp" command to ignore read
  9934. errors while copying. (omalley via cutting)
  9935. 19. HADOOP-27. Don't allocate tasks to trackers whose local free
  9936. space is too low. (Johan Oskarson via cutting)
  9937. 20. HADOOP-318. Keep slow DFS output from causing task timeouts.
  9938. This incompatibly changes some public interfaces, adding a
  9939. parameter to OutputFormat.getRecordWriter() and the new method
  9940. Reporter.progress(), but it makes lots of tasks succeed that were
  9941. previously failing. (Milind Bhandarkar via cutting)
  9942. Release 0.3.2 - 2006-06-09
  9943. 1. HADOOP-275. Update the streaming contrib module to use log4j for
  9944. its logging. (Michel Tourn via cutting)
  9945. 2. HADOOP-279. Provide defaults for log4j logging parameters, so
  9946. that things still work reasonably when Hadoop-specific system
  9947. properties are not provided. (omalley via cutting)
  9948. 3. HADOOP-280. Fix a typo in AllTestDriver which caused the wrong
  9949. test to be run when "DistributedFSCheck" was specified.
  9950. (Konstantin Shvachko via cutting)
  9951. 4. HADOOP-240. DFS's mkdirs() implementation no longer logs a warning
  9952. when the directory already exists. (Hairong Kuang via cutting)
  9953. 5. HADOOP-285. Fix DFS datanodes to be able to re-join the cluster
  9954. after the connection to the namenode is lost. (omalley via cutting)
  9955. 6. HADOOP-277. Fix a race condition when creating directories.
  9956. (Sameer Paranjpye via cutting)
  9957. 7. HADOOP-289. Improved exception handling in DFS datanode.
  9958. (Konstantin Shvachko via cutting)
  9959. 8. HADOOP-292. Fix client-side logging to go to standard error
  9960. rather than standard output, so that it can be distinguished from
  9961. application output. (omalley via cutting)
  9962. 9. HADOOP-294. Fixed bug where conditions for retrying after errors
  9963. in the DFS client were reversed. (omalley via cutting)
  9964. Release 0.3.1 - 2006-06-05
  9965. 1. HADOOP-272. Fix a bug in bin/hadoop setting log
  9966. parameters. (omalley & cutting)
  9967. 2. HADOOP-274. Change applications to log to standard output rather
  9968. than to a rolling log file like daemons. (omalley via cutting)
  9969. 3. HADOOP-262. Fix reduce tasks to report progress while they're
  9970. waiting for map outputs, so that they do not time out.
  9971. (Mahadev Konar via cutting)
  9972. 4. HADOOP-245 and HADOOP-246. Improvements to record io package.
  9973. (Mahadev Konar via cutting)
  9974. 5. HADOOP-276. Add logging config files to jar file so that they're
  9975. always found. (omalley via cutting)
  9976. Release 0.3.0 - 2006-06-02
  9977. 1. HADOOP-208. Enhance MapReduce web interface, adding new pages
  9978. for failed tasks, and tasktrackers. (omalley via cutting)
  9979. 2. HADOOP-204. Tweaks to metrics package. (David Bowen via cutting)
  9980. 3. HADOOP-209. Add a MapReduce-based file copier. This will
  9981. copy files within or between file systems in parallel.
  9982. (Milind Bhandarkar via cutting)
  9983. 4. HADOOP-146. Fix DFS to check when randomly generating a new block
  9984. id that no existing blocks already have that id.
  9985. (Milind Bhandarkar via cutting)
  9986. 5. HADOOP-180. Make a daemon thread that does the actual task clean ups, so
  9987. that the main offerService thread in the taskTracker doesn't get stuck
  9988. and miss his heartbeat window. This was killing many task trackers as
  9989. big jobs finished (300+ tasks / node). (omalley via cutting)
  9990. 6. HADOOP-200. Avoid transmitting entire list of map task names to
  9991. reduce tasks. Instead just transmit the number of map tasks and
  9992. henceforth refer to them by number when collecting map output.
  9993. (omalley via cutting)
  9994. 7. HADOOP-219. Fix a NullPointerException when handling a checksum
  9995. exception under SequenceFile.Sorter.sort(). (cutting & stack)
  9996. 8. HADOOP-212. Permit alteration of the file block size in DFS. The
  9997. default block size for new files may now be specified in the
  9998. configuration with the dfs.block.size property. The block size
  9999. may also be specified when files are opened.
  10000. (omalley via cutting)
  10001. 9. HADOOP-218. Avoid accessing configuration while looping through
  10002. tasks in JobTracker. (Mahadev Konar via cutting)
  10003. 10. HADOOP-161. Add hashCode() method to DFS's Block.
  10004. (Milind Bhandarkar via cutting)
  10005. 11. HADOOP-115. Map output types may now be specified. These are also
  10006. used as reduce input types, thus permitting reduce input types to
  10007. differ from reduce output types. (Runping Qi via cutting)
  10008. 12. HADOOP-216. Add task progress to task status page.
  10009. (Bryan Pendelton via cutting)
  10010. 13. HADOOP-233. Add web server to task tracker that shows running
  10011. tasks and logs. Also add log access to job tracker web interface.
  10012. (omalley via cutting)
  10013. 14. HADOOP-205. Incorporate pending tasks into tasktracker load
  10014. calculations. (Mahadev Konar via cutting)

  10017. 16. HADOOP-195. Improve performance of the transfer of map outputs to
  10018. reduce nodes by performing multiple transfers in parallel, each on
  10019. a separate socket. (Sameer Paranjpye via cutting)
  10020. 17. HADOOP-251. Fix task processes to be tolerant of failed progress
  10021. reports to their parent process. (omalley via cutting)
  10022. 18. HADOOP-325. Improve the FileNotFound exceptions thrown by
  10023. LocalFileSystem to include the name of the file.
  10024. (Benjamin Reed via cutting)
  10025. 19. HADOOP-254. Use HTTP to transfer map output data to reduce
  10026. nodes. This, together with HADOOP-195, greatly improves the
  10027. performance of these transfers. (omalley via cutting)
  10028. 20. HADOOP-163. Cause datanodes that\ are unable to either read or
  10029. write data to exit, so that the namenode will no longer target
  10030. them for new blocks and will replicate their data on other nodes.
  10031. (Hairong Kuang via cutting)
  10032. 21. HADOOP-222. Add a -setrep option to the dfs commands that alters
  10033. file replication levels. (Johan Oskarson via cutting)
  10034. 22. HADOOP-75. In DFS, only check for a complete file when the file
  10035. is closed, rather than as each block is written.
  10036. (Milind Bhandarkar via cutting)
  10037. 23. HADOOP-124. Change DFS so that datanodes are identified by a
  10038. persistent ID rather than by host and port. This solves a number
  10039. of filesystem integrity problems, when, e.g., datanodes are
  10040. restarted. (Konstantin Shvachko via cutting)
  10041. 24. HADOOP-256. Add a C API for DFS. (Arun C Murthy via cutting)
  10042. 25. HADOOP-211. Switch to use the Jakarta Commons logging internally,
  10043. configured to use log4j by default. (Arun C Murthy and cutting)
  10044. 26. HADOOP-265. Tasktracker now fails to start if it does not have a
  10045. writable local directory for temporary files. In this case, it
  10046. logs a message to the JobTracker and exits. (Hairong Kuang via cutting)
  10047. 27. HADOOP-270. Fix potential deadlock in datanode shutdown.
  10048. (Hairong Kuang via cutting)
  10049. Release 0.2.1 - 2006-05-12
  10050. 1. HADOOP-199. Fix reduce progress (broken by HADOOP-182).
  10051. (omalley via cutting)
  10052. 2. HADOOP-201. Fix 'bin/hadoop dfs -report'. (cutting)
  10053. 3. HADOOP-207. Fix JDK 1.4 incompatibility introduced by HADOOP-96.
  10054. System.getenv() does not work in JDK 1.4. (Hairong Kuang via cutting)
  10055. Release 0.2.0 - 2006-05-05
  10056. 1. Fix HADOOP-126. 'bin/hadoop dfs -cp' now correctly copies .crc
  10057. files. (Konstantin Shvachko via cutting)
  10058. 2. Fix HADOOP-51. Change DFS to support per-file replication counts.
  10059. (Konstantin Shvachko via cutting)
  10060. 3. Fix HADOOP-131. Add scripts to start/stop dfs and mapred daemons.
  10061. Use these in start/stop-all scripts. (Chris Mattmann via cutting)
  10062. 4. Stop using ssh options by default that are not yet in widely used
  10063. versions of ssh. Folks can still enable their use by uncommenting
  10064. a line in conf/hadoop-env.sh. (cutting)
  10065. 5. Fix HADOOP-92. Show information about all attempts to run each
  10066. task in the web ui. (Mahadev konar via cutting)
  10067. 6. Fix HADOOP-128. Improved DFS error handling. (Owen O'Malley via cutting)
  10068. 7. Fix HADOOP-129. Replace uses of java.io.File with new class named
  10069. Path. This fixes bugs where java.io.File methods were called
  10070. directly when FileSystem methods were desired, and reduces the
  10071. likelihood of such bugs in the future. It also makes the handling
  10072. of pathnames more consistent between local and dfs FileSystems and
  10073. between Windows and Unix. java.io.File-based methods are still
  10074. available for back-compatibility, but are deprecated and will be
  10075. removed once 0.2 is released. (cutting)
  10076. 8. Change dfs.data.dir and mapred.local.dir to be comma-separated
  10077. lists of directories, no longer be space-separated. This fixes
  10078. several bugs on Windows. (cutting)
  10079. 9. Fix HADOOP-144. Use mapred task id for dfs client id, to
  10080. facilitate debugging. (omalley via cutting)
  10081. 10. Fix HADOOP-143. Do not line-wrap stack-traces in web ui.
  10082. (omalley via cutting)
  10083. 11. Fix HADOOP-118. In DFS, improve clean up of abandoned file
  10084. creations. (omalley via cutting)
  10085. 12. Fix HADOOP-138. Stop multiple tasks in a single heartbeat, rather
  10086. than one per heartbeat. (Stefan via cutting)
  10087. 13. Fix HADOOP-139. Remove a potential deadlock in
  10088. LocalFileSystem.lock(). (Igor Bolotin via cutting)
  10089. 14. Fix HADOOP-134. Don't hang jobs when the tasktracker is
  10090. misconfigured to use an un-writable local directory. (omalley via cutting)
  10091. 15. Fix HADOOP-115. Correct an error message. (Stack via cutting)
  10092. 16. Fix HADOOP-133. Retry pings from child to parent, in case of
  10093. (local) communcation problems. Also log exit status, so that one
  10094. can distinguish patricide from other deaths. (omalley via cutting)
  10095. 17. Fix HADOOP-142. Avoid re-running a task on a host where it has
  10096. previously failed. (omalley via cutting)
  10097. 18. Fix HADOOP-148. Maintain a task failure count for each
  10098. tasktracker and display it in the web ui. (omalley via cutting)
  10099. 19. Fix HADOOP-151. Close a potential socket leak, where new IPC
  10100. connection pools were created per configuration instance that RPCs
  10101. use. Now a global RPC connection pool is used again, as
  10102. originally intended. (cutting)
  10103. 20. Fix HADOOP-69. Don't throw a NullPointerException when getting
  10104. hints for non-existing file split. (Bryan Pendelton via cutting)
  10105. 21. Fix HADOOP-157. When a task that writes dfs files (e.g., a reduce
  10106. task) failed and was retried, it would fail again and again,
  10107. eventually failing the job. The problem was that dfs did not yet
  10108. know that the failed task had abandoned the files, and would not
  10109. yet let another task create files with the same names. Dfs now
  10110. retries when creating a file long enough for locks on abandoned
  10111. files to expire. (omalley via cutting)
  10112. 22. Fix HADOOP-150. Improved task names that include job
  10113. names. (omalley via cutting)
  10114. 23. Fix HADOOP-162. Fix ConcurrentModificationException when
  10115. releasing file locks. (omalley via cutting)
  10116. 24. Fix HADOOP-132. Initial check-in of new Metrics API, including
  10117. implementations for writing metric data to a file and for sending
  10118. it to Ganglia. (David Bowen via cutting)
  10119. 25. Fix HADOOP-160. Remove some uneeded synchronization around
  10120. time-consuming operations in the TaskTracker. (omalley via cutting)
  10121. 26. Fix HADOOP-166. RPCs failed when passed subclasses of a declared
  10122. parameter type. This is fixed by changing ObjectWritable to store
  10123. both the declared type and the instance type for Writables. Note
  10124. that this incompatibly changes the format of ObjectWritable and
  10125. will render unreadable any ObjectWritables stored in files.
  10126. Nutch only uses ObjectWritable in intermediate files, so this
  10127. should not be a problem for Nutch. (Stefan & cutting)
  10128. 27. Fix HADOOP-168. MapReduce RPC protocol methods should all declare
  10129. IOException, so that timeouts are handled appropriately.
  10130. (omalley via cutting)
  10131. 28. Fix HADOOP-169. Don't fail a reduce task if a call to the
  10132. jobtracker to locate map outputs fails. (omalley via cutting)
  10133. 29. Fix HADOOP-170. Permit FileSystem clients to examine and modify
  10134. the replication count of individual files. Also fix a few
  10135. replication-related bugs. (Konstantin Shvachko via cutting)
  10136. 30. Permit specification of a higher replication levels for job
  10137. submission files (job.xml and job.jar). This helps with large
  10138. clusters, since these files are read by every node. (cutting)
  10139. 31. HADOOP-173. Optimize allocation of tasks with local data. (cutting)
  10140. 32. HADOOP-167. Reduce number of Configurations and JobConf's
  10141. created. (omalley via cutting)
  10142. 33. NUTCH-256. Change FileSystem#createNewFile() to create a .crc
  10143. file. The lack of a .crc file was causing warnings. (cutting)
  10144. 34. HADOOP-174. Change JobClient to not abort job until it has failed
  10145. to contact the job tracker for five attempts, not just one as
  10146. before. (omalley via cutting)
  10147. 35. HADOOP-177. Change MapReduce web interface to page through tasks.
  10148. Previously, when jobs had more than a few thousand tasks they
  10149. could crash web browsers. (Mahadev Konar via cutting)
  10150. 36. HADOOP-178. In DFS, piggyback blockwork requests from datanodes
  10151. on heartbeat responses from namenode. This reduces the volume of
  10152. RPC traffic. Also move startup delay in blockwork from datanode
  10153. to namenode. This fixes a problem where restarting the namenode
  10154. triggered a lot of uneeded replication. (Hairong Kuang via cutting)
  10155. 37. HADOOP-183. If the DFS namenode is restarted with different
  10156. minimum and/or maximum replication counts, existing files'
  10157. replication counts are now automatically adjusted to be within the
  10158. newly configured bounds. (Hairong Kuang via cutting)
  10159. 38. HADOOP-186. Better error handling in TaskTracker's top-level
  10160. loop. Also improve calculation of time to send next heartbeat.
  10161. (omalley via cutting)
  10162. 39. HADOOP-187. Add two MapReduce examples/benchmarks. One creates
  10163. files containing random data. The second sorts the output of the
  10164. first. (omalley via cutting)
  10165. 40. HADOOP-185. Fix so that, when a task tracker times out making the
  10166. RPC asking for a new task to run, the job tracker does not think
  10167. that it is actually running the task returned. (omalley via cutting)
  10168. 41. HADOOP-190. If a child process hangs after it has reported
  10169. completion, its output should not be lost. (Stack via cutting)
  10170. 42. HADOOP-184. Re-structure some test code to better support testing
  10171. on a cluster. (Mahadev Konar via cutting)
  10172. 43. HADOOP-191 Add streaming package, Hadoop's first contrib module.
  10173. This permits folks to easily submit MapReduce jobs whose map and
  10174. reduce functions are implemented by shell commands. Use
  10175. 'bin/hadoop jar build/hadoop-streaming.jar' to get details.
  10176. (Michel Tourn via cutting)
  10177. 44. HADOOP-189. Fix MapReduce in standalone configuration to
  10178. correctly handle job jar files that contain a lib directory with
  10179. nested jar files. (cutting)
  10180. 45. HADOOP-65. Initial version of record I/O framework that enables
  10181. the specification of record types and generates marshalling code
  10182. in both Java and C++. Generated Java code implements
  10183. WritableComparable, but is not yet otherwise used by
  10184. Hadoop. (Milind Bhandarkar via cutting)
  10185. 46. HADOOP-193. Add a MapReduce-based FileSystem benchmark.
  10186. (Konstantin Shvachko via cutting)
  10187. 47. HADOOP-194. Add a MapReduce-based FileSystem checker. This reads
  10188. every block in every file in the filesystem. (Konstantin Shvachko
  10189. via cutting)
  10190. 48. HADOOP-182. Fix so that lost task trackers to not change the
  10191. status of reduce tasks or completed jobs. Also fixes the progress
  10192. meter so that failed tasks are subtracted. (omalley via cutting)
  10193. 49. HADOOP-96. Logging improvements. Log files are now separate from
  10194. standard output and standard error files. Logs are now rolled.
  10195. Logging of all DFS state changes can be enabled, to facilitate
  10196. debugging. (Hairong Kuang via cutting)
  10197. Release 0.1.1 - 2006-04-08
  10198. 1. Added CHANGES.txt, logging all significant changes to Hadoop. (cutting)
  10199. 2. Fix MapReduceBase.close() to throw IOException, as declared in the
  10200. Closeable interface. This permits subclasses which override this
  10201. method to throw that exception. (cutting)
  10202. 3. Fix HADOOP-117. Pathnames were mistakenly transposed in
  10203. JobConf.getLocalFile() causing many mapred temporary files to not
  10204. be removed. (Raghavendra Prabhu via cutting)
  10205. 4. Fix HADOOP-116. Clean up job submission files when jobs complete.
  10206. (cutting)
  10207. 5. Fix HADOOP-125. Fix handling of absolute paths on Windows (cutting)
  10208. Release 0.1.0 - 2006-04-01
  10209. 1. The first release of Hadoop.
