---
-* [HADOOP-3837](https://issues.apache.org/jira/browse/HADOOP-3837) | *Major* | **hadop streaming does not use progress reporting to detect hung tasks**
+* [HADOOP-2585](https://issues.apache.org/jira/browse/HADOOP-2585) | *Major* | **Automatic namespace recovery from the secondary image.**
-Changed streaming tasks to adhere to task timeout value specified in the job configuration.
+Improved management of replicas of the name space image. If all replicas on the Name Node are lost, the latest check point can be loaded from the secondary Name Node. Use parameter "-importCheckpoint" and specify the location with "fs.checkpoint.dir." The directory structure on the secondary Name Node has changed to match the primary Name Node.
---
-* [HADOOP-3808](https://issues.apache.org/jira/browse/HADOOP-3808) | *Blocker* | **[HOD] Include job tracker RPC in notes attribute after job submission**
+* [HADOOP-2703](https://issues.apache.org/jira/browse/HADOOP-2703) | *Minor* | **New files under lease (before close) still shows up as MISSING files/blocks in fsck**
-Modified HOD to include the RPC port of the JobTracker in the 'notes' attribute of the resource manager. The RPC port is included as the string 'Mapred RPC Port:\<port number\>'. Tools that depend on the value of the notes attribute must change to parse this new value.
+Changed fsck to ignore files opened for writing. Introduced new option "-openforwrite" to explicitly show open files.
---
-* [HADOOP-3703](https://issues.apache.org/jira/browse/HADOOP-3703) | *Blocker* | **[HOD] logcondense needs to use the new pattern of output in hadoop dfs -lsr**
+* [HADOOP-2865](https://issues.apache.org/jira/browse/HADOOP-2865) | *Major* | **FsShell.ls() should print file attributes first then the path name.**
-Modified logcondense.py to use the new format of hadoop dfs -lsr output. This version of logcondense would not work with previous versions of Hadoop and hence is incompatible.
+Changed the output of the "fs -ls" command to more closely match familiar Linux format. Additional changes were made by HADOOP-3459. Applications that parse the command output should be reviewed.
---
-* [HADOOP-3683](https://issues.apache.org/jira/browse/HADOOP-3683) | *Major* | **Hadoop dfs metric FilesListed shows number of files listed instead of operations**
+* [HADOOP-3061](https://issues.apache.org/jira/browse/HADOOP-3061) | *Major* | **Writable for single byte and double**

-Simplify generation stamp upgrade by making is a local upgrade on datandodes. Deleted distributed upgrade.
+Changed data node to use FileChannel.tranferTo() to transfer block data.
---
-* [HADOOP-3665](https://issues.apache.org/jira/browse/HADOOP-3665) | *Minor* | **WritableComparator newKey() fails for NullWritable**

+Changed the serialization in DatanodeRegistration and DatanodeInfo, and therefore, updated the versionID in ClientProtocol, DatanodeProtocol, NamenodeProtocol.
---
-* [HADOOP-3610](https://issues.apache.org/jira/browse/HADOOP-3610) | *Blocker* | **[HOD] HOD does not automatically create a cluster directory for the script option**
+* [HADOOP-2797](https://issues.apache.org/jira/browse/HADOOP-2797) | *Critical* | **Withdraw CRC upgrade from HDFS**
-Modified HOD to automatically create a cluster directory if the one specified with the script command does not exist.
+Withdrew the upgrade-to-CRC facility. HDFS will no longer support upgrades from versions without CRCs for block data. Users upgrading from version 0.13 or earlier must first upgrade to an intermediate (0.14, 0.15, 0.16, 0.17) version before doing upgrade to version 0.18 or later.
---
-* [HADOOP-3598](https://issues.apache.org/jira/browse/HADOOP-3598) | *Blocker* | **Map-Reduce framework needlessly creates temporary \_${taskid} directories for Maps**
+* [HADOOP-544](https://issues.apache.org/jira/browse/HADOOP-544) | *Major* | **Replace the job, tip and task ids with objects.**
-Changed Map-Reduce framework to no longer create temporary task output directories for staging outputs if staging outputs isn't necessary. ${mapred.out.dir}/\_temporary/\_${taskid}
+Introduced new classes JobID, TaskID and TaskAttemptID, which should be used instead of their string counterparts. Deprecated functions in JobClient, TaskReport, RunningJob, jobcontrol.Job and TaskCompletionEvent that use string arguments. Applications can use xxxID.toString() and xxxID.forName() methods to convert/restore objects to/from strings.

+* [HADOOP-3486](https://issues.apache.org/jira/browse/HADOOP-3486) | *Major* | **Change default for initial block report to 0 sec and document it in hadoop-defaults.xml**
-Changed policy for running combiner. The combiner may be run multiple times as the map's output is sorted and merged. Additionally, it may be run on the reduce side as data is merged. The old semantics are available in Hadoop 0.18 if the user calls:
-job.setCombineOnlyOnce(true);
+Changed the default value of dfs.blockreport.initialDelay to be 0 seconds.
---
-* [HADOOP-3221](https://issues.apache.org/jira/browse/HADOOP-3221) | *Major* | **Need a "LineBasedTextInputFormat"**

-* [HADOOP-3187](https://issues.apache.org/jira/browse/HADOOP-3187) | *Major* | **Quotas for name space management**
+* [HADOOP-3113](https://issues.apache.org/jira/browse/HADOOP-3113) | *Major* | **DFSOututStream.flush() should flush data to real block file on DataNode.**
-Introduced directory quota as hard limits on the number of names in the tree rooted at that directory. An administrator may set quotas on individual directories explicitly. Newly created directories have no associated quota. File/directory creations fault if the quota would be exceeded. The attempt to set a quota faults if the directory would be in violation of the new quota.
+Added sync() method to FSDataOutputStream to really, really persist data in HDFS. InterDatanodeProtocol to implement this feature.

-* [HADOOP-3184](https://issues.apache.org/jira/browse/HADOOP-3184) | *Major* | **HOD gracefully exclude "bad" nodes during ring formation**
+* [HADOOP-3464](https://issues.apache.org/jira/browse/HADOOP-3464) | *Major* | **[HOD] HOD can improve error messages by reporting failures on compute nodes back to hod client**
-Modified HOD to handle master (NameNode or JobTracker) failures on bad nodes by trying to bring them up on another node in the ring. Introduced new property ringmaster.max-master-failures to specify the maximum number of times a master is allowed to fail.
+Implemented a mechanism to transfer HOD errors that occur on compute nodes to the submit node running the HOD client, so users have good feedback on why an allocation failed.
---
-* [HADOOP-3177](https://issues.apache.org/jira/browse/HADOOP-3177) | *Major* | **Expose DFSOutputStream.fsync API though the FileSystem interface**
+* [HADOOP-3452](https://issues.apache.org/jira/browse/HADOOP-3452) | *Minor* | **fsck exit code would be better if non-zero when FS corrupt**
-Added a new public interface Syncable which declares the sync() operation. FSDataOutputStream implements Syncable. If the wrappedStream in FSDataOutputStream is Syncalbe, calling FSDataOutputStream.sync() is equivalent to call wrappedStream.sync(). Otherwise, FSDataOutputStream.sync() is a no-op. Both DistributedFileSystem and LocalFileSystem support the sync() operation.
+Changed exit status of fsck to report whether the files system is healthy or corrupt.
---
-* [HADOOP-3164](https://issues.apache.org/jira/browse/HADOOP-3164) | *Major* | **Use FileChannel.transferTo() when data is read from DataNode.**
+* [HADOOP-1328](https://issues.apache.org/jira/browse/HADOOP-1328) | *Major* | **Hadoop Streaming needs to provide a way for the stream plugin to update global counters**
-Changed data node to use FileChannel.tranferTo() to transfer block data.
+Introduced a way for a streaming process to update global counters and status using stderr stream to emit information. Use "reporter:counter:\<group\>,\<counter\>,\<amount\> " to update a counter. Use "reporter:status:\<message\>" to update status.
---
-* [HADOOP-3135](https://issues.apache.org/jira/browse/HADOOP-3135) | *Critical* | **if the 'mapred.system.dir' in the client jobconf is different from the JobTracker's value job submission fails**
+* [HADOOP-3095](https://issues.apache.org/jira/browse/HADOOP-3095) | *Major* | **Validating input paths and creating splits is slow on S3**
-Changed job submission protocol to not allow submission if the client's value of mapred.system.dir does not match the job tracker's. Deprecated JobConf.getSystemDir(); use JobClient.getSystemDir().
+Added overloaded method getFileBlockLocations(FileStatus, long, long). This is an incompatible change for FileSystem implementations which override getFileBlockLocations(Path, long, long). They should have the signature of this method changed to getFileBlockLocations(FileStatus, long, long) to work correctly.
---
-* [HADOOP-3113](https://issues.apache.org/jira/browse/HADOOP-3113) | *Major* | **DFSOututStream.flush() should flush data to real block file on DataNode.**
+* [HADOOP-2095](https://issues.apache.org/jira/browse/HADOOP-2095) | *Major* | **Reducer failed due to Out ofMemory**
-Added sync() method to FSDataOutputStream to really, really persist data in HDFS. InterDatanodeProtocol to implement this feature.
+Reduced in-memory copies of keys and values as they flow through the Map-Reduce framework. Changed the storage of intermediate map outputs to use new IFile instead of SequenceFile for better compression.

+* [HADOOP-2427](https://issues.apache.org/jira/browse/HADOOP-2427) | *Major* | **Cleanup of mapred.local.dir after maptask is complete**
-Added overloaded method getFileBlockLocations(FileStatus, long, long). This is an incompatible change for FileSystem implementations which override getFileBlockLocations(Path, long, long). They should have the signature of this method changed to getFileBlockLocations(FileStatus, long, long) to work correctly.
+The current working directory of a task, i.e. ${mapred.local.dir}/taskTracker/jobcache/\<jobid\>/\<task\_dir\>/work is cleanedup, as soon as the task is finished.
---
-* [HADOOP-3061](https://issues.apache.org/jira/browse/HADOOP-3061) | *Major* | **Writable for single byte and double**
+* [HADOOP-3187](https://issues.apache.org/jira/browse/HADOOP-3187) | *Major* | **Quotas for name space management**
-Introduced ByteWritable and DoubleWritable (implementing WritableComparable) implementations for Byte and Double.
+Introduced directory quota as hard limits on the number of names in the tree rooted at that directory. An administrator may set quotas on individual directories explicitly. Newly created directories have no associated quota. File/directory creations fault if the quota would be exceeded. The attempt to set a quota faults if the directory would be in violation of the new quota.
---
-* [HADOOP-3058](https://issues.apache.org/jira/browse/HADOOP-3058) | *Minor* | **Hadoop DFS to report more replication metrics**
+* [HADOOP-3307](https://issues.apache.org/jira/browse/HADOOP-3307) | *Major* | **Archives in Hadoop.**
-Added FSNamesystem status metrics.

-* [HADOOP-3035](https://issues.apache.org/jira/browse/HADOOP-3035) | *Major* | **Data nodes should inform the name-node about block crc errors.**
+* [HADOOP-3326](https://issues.apache.org/jira/browse/HADOOP-3326) | *Major* | **ReduceTask should not sleep for 200 ms while waiting for merge to finish**
-Changed protocol for transferring blocks between data nodes to report corrupt blocks to data node for re-replication from a good replica.
+Changed fetchOutputs() so that LocalFSMerger and InMemFSMergeThread threads are spawned only once. The thread gets notified when something is ready for merge. The merge happens when thresholds are met.
---
-* [HADOOP-3013](https://issues.apache.org/jira/browse/HADOOP-3013) | *Major* | **fsck to show (checksum) corrupted files**

-Added task's cwd to its LD\_LIBRARY\_PATH.
+Changed shuffle scheduler policy to wait for notifications from shuffle threads before scheduling more.
---
-* [HADOOP-2865](https://issues.apache.org/jira/browse/HADOOP-2865) | *Major* | **FsShell.ls() should print file attributes first then the path name.**
+* [HADOOP-3184](https://issues.apache.org/jira/browse/HADOOP-3184) | *Major* | **HOD gracefully exclude "bad" nodes during ring formation**
-Changed the output of the "fs -ls" command to more closely match familiar Linux format. Additional changes were made by HADOOP-3459. Applications that parse the command output should be reviewed.
+Modified HOD to handle master (NameNode or JobTracker) failures on bad nodes by trying to bring them up on another node in the ring. Introduced new property ringmaster.max-master-failures to specify the maximum number of times a master is allowed to fail.
---
-* [HADOOP-2797](https://issues.apache.org/jira/browse/HADOOP-2797) | *Critical* | **Withdraw CRC upgrade from HDFS**
+* [HADOOP-3135](https://issues.apache.org/jira/browse/HADOOP-3135) | *Critical* | **if the 'mapred.system.dir' in the client jobconf is different from the JobTracker's value job submission fails**
-Withdrew the upgrade-to-CRC facility. HDFS will no longer support upgrades from versions without CRCs for block data. Users upgrading from version 0.13 or earlier must first upgrade to an intermediate (0.14, 0.15, 0.16, 0.17) version before doing upgrade to version 0.18 or later.
+Changed job submission protocol to not allow submission if the client's value of mapred.system.dir does not match the job tracker's. Deprecated JobConf.getSystemDir(); use JobClient.getSystemDir().
---
-* [HADOOP-2703](https://issues.apache.org/jira/browse/HADOOP-2703) | *Minor* | **New files under lease (before close) still shows up as MISSING files/blocks in fsck**
+* [HADOOP-3460](https://issues.apache.org/jira/browse/HADOOP-3460) | *Minor* | **SequenceFileAsBinaryOutputFormat**
-Changed fsck to ignore files opened for writing. Introduced new option "-openforwrite" to explicitly show open files.
+Created SequenceFileAsBinaryOutputFormat to write raw bytes as keys and values to a SequenceFile.
---
-* [HADOOP-2656](https://issues.apache.org/jira/browse/HADOOP-2656) | *Major* | **Support for upgrading existing cluster to facilitate appends to HDFS files**
+* [HADOOP-3230](https://issues.apache.org/jira/browse/HADOOP-3230) | *Major* | **Add command line access to named counters**
-Associated a generation stamp with each block. On data nodes, the generation stamp is stored as part of the file name of the block's meta-data file.
+Added command line tool "job -counter \<job-id\> \<group-name\> \<counter-name\>" to access counters.
---
-* [HADOOP-2585](https://issues.apache.org/jira/browse/HADOOP-2585) | *Major* | **Automatic namespace recovery from the secondary image.**
+* [HADOOP-930](https://issues.apache.org/jira/browse/HADOOP-930) | *Major* | **Add support for reading regular (non-block-based) files from S3 in S3FileSystem**
-Improved management of replicas of the name space image. If all replicas on the Name Node are lost, the latest check point can be loaded from the secondary Name Node. Use parameter "-importCheckpoint" and specify the location with "fs.checkpoint.dir." The directory structure on the secondary Name Node has changed to match the primary Name Node.
+Added support for reading and writing native S3 files. Native S3 files are referenced using s3n URIs. See http://wiki.apache.org/hadoop/AmazonS3 for more details.
---
-* [HADOOP-2427](https://issues.apache.org/jira/browse/HADOOP-2427) | *Major* | **Cleanup of mapred.local.dir after maptask is complete**
+* [HADOOP-3193](https://issues.apache.org/jira/browse/HADOOP-3193) | *Minor* | **Discovery of corrupt block reported in name node log**

+Added reporter to FSNamesystem stateChangeLog, and a new metric to track the number of corrupted replicas.
---
-* [HADOOP-2188](https://issues.apache.org/jira/browse/HADOOP-2188) | *Major* | **RPC should send a ping rather than use client timeouts**
+* [HADOOP-3366](https://issues.apache.org/jira/browse/HADOOP-3366) | *Major* | **Shuffle/Merge improvements**
-Replaced timeouts with pings to check that client connection is alive. Removed the property ipc.client.timeout from the default Hadoop configuration. Removed the metric RpcOpsDiscardedOPsNum.
+Improved shuffle so that all fetched map-outputs are kept in-memory before being merged by stalling the shuffle so that the in-memory merge executes and frees up memory for the shuffle.

---
-* [HADOOP-1915](https://issues.apache.org/jira/browse/HADOOP-1915) | *Minor* | **adding counters methods using String (as opposed to Enum)**
+* [HADOOP-3610](https://issues.apache.org/jira/browse/HADOOP-3610) | *Blocker* | **[HOD] HOD does not automatically create a cluster directory for the script option**
-Provided a new method to update counters. "incrCounter(String group, String counter, long amount)"
+Modified HOD to automatically create a cluster directory if the one specified with the script command does not exist.
---
-* [HADOOP-1702](https://issues.apache.org/jira/browse/HADOOP-1702) | *Major* | **Reduce buffer copies when data is written to DFS**
+* [HADOOP-3665](https://issues.apache.org/jira/browse/HADOOP-3665) | *Minor* | **WritableComparator newKey() fails for NullWritable**

+Change FileListed to getNumGetListingOps and add CreateFileOps, DeleteFileOps and AddBlockOps metrics.
---
-* [HADOOP-930](https://issues.apache.org/jira/browse/HADOOP-930) | *Major* | **Add support for reading regular (non-block-based) files from S3 in S3FileSystem**
+* [HADOOP-3703](https://issues.apache.org/jira/browse/HADOOP-3703) | *Blocker* | **[HOD] logcondense needs to use the new pattern of output in hadoop dfs -lsr**
-Added support for reading and writing native S3 files. Native S3 files are referenced using s3n URIs. See http://wiki.apache.org/hadoop/AmazonS3 for more details.
+Modified logcondense.py to use the new format of hadoop dfs -lsr output. This version of logcondense would not work with previous versions of Hadoop and hence is incompatible.

-Changed connection protocol job tracker and task tracker so that task tracker will not connect to a job tracker with a different build version.
+Modified HOD to include the RPC port of the JobTracker in the 'notes' attribute of the resource manager. The RPC port is included as the string 'Mapred RPC Port:\<port number\>'. Tools that depend on the value of the notes attribute must change to parse this new value.
---
-* [HADOOP-4](https://issues.apache.org/jira/browse/HADOOP-4) | *Major* | **tool to mount dfs on linux**
+* [HADOOP-3837](https://issues.apache.org/jira/browse/HADOOP-3837) | *Major* | **hadop streaming does not use progress reporting to detect hung tasks**
