These release notes cover new developer and user-facing incompatibilities, important issues, features, and major improvements.

  • HADOOP-11801 MinorUpdate BUILDING.txt for Ubuntu
Hadoop 2.7 1 Winutils Exe Download

ProtocolBuffer is packaged in Ubuntu

  • HADOOP-11498 MajorBump the version of HTrace to 3.1.0-incubating

WARNING: No release note provided for this incompatible change.

  • HADOOP-11492 MajorBump up curator version to 2.7.1

Apache Curator version change: Apache Hadoop has updated the version of Apache Curator used from 2.6.0 to 2.7.1. This change should be binary and source compatible for the majority of downstream users. Notable exceptions:

  • Binary incompatible change: org.apache.curator.utils.PathUtils.validatePath(String) changed return types. Downstream users of this method will need to recompile.
  • Source incompatible change: org.apache.curator.framework.recipes.shared.SharedCountReader added a method to its interface definition. Downstream users with custom implementations of this interface can continue without binary compatibility problems but will need to modify their source code to recompile.
  • Source incompatible change: org.apache.curator.framework.recipes.shared.SharedValueReader added a method to its interface definition. Downstream users with custom implementations of this interface can continue without binary compatibility problems but will need to modify their source code to recompile.

Downstream users are reminded that while the Hadoop community will attempt to avoid egregious incompatible dependency changes, there is currently no policy around when Hadoop’s exposed dependencies will change across versions (ref http://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-common/Compatibility.html#Java_Classpath ).

  • HADOOP-11464 MajorReinstate support for launching Hadoop processes on Windows using Cygwin.

We have reinstated support for launching Hadoop processes on Windows by using Cygwin to run the shell scripts. All processes still must have access to the native components: hadoop.dll and winutils.exe.

  • HADOOP-11446 MajorS3AOutputStream should use shared thread pool to avoid OutOfMemoryError

The following parameters are introduced in this JIRA: fs.s3a.threads.max: the maximum number of threads to allow in the pool used by TransferManager fs.s3a.threads.core: the number of threads to keep in the pool used by TransferManager fs.s3a.threads.keepalivetime: when the number of threads is greater than the core, this is the maximum time that excess idle threads will wait for new tasks before terminating fs.s3a.max.total.tasks: the maximum number of tasks that the LinkedBlockingQueue can hold

  • HADOOP-11385 CriticalPrevent cross site scripting attack on JMXJSONServlet

WARNING: No release note provided for this incompatible change.

  • HADOOP-11311 MajorRestrict uppercase key names from being created with JCEKS

Keys with uppercase names can no longer be created when using the JavaKeyStoreProvider to resolve ambiguity about case-sensitivity in the KeyStore spec.

  • HADOOP-10530 BlockerMake hadoop trunk build on Java7+ only

WARNING: No release note provided for this incompatible change.

  • HADOOP-10181 MinorGangliaContext does not work with multicast ganglia setup

Hadoop metrics sent to Ganglia over multicast now support optional configuration of socket TTL. The default TTL is 1, which preserves the behavior of prior Hadoop versions. Clusters that span multiple subnets/VLANs will likely want to increase this.

  • HADOOP-9922 Majorhadoop windows native build will fail in 32 bit machine

The Hadoop Common native components now support 32-bit build targets on Windows.

  • HADOOP-9629 MajorSupport Windows Azure Storage - Blob as a file system in Hadoop

Hadoop 2.7 1 Winutils Exe Download 32-bit

Hadoop now supports integration with Azure Storage as an alternative Hadoop Compatible File System.

  • HADOOP-9329 Trivialdocument native build dependencies in BUILDING.txt

Added a section to BUILDING.txt on how to install required / optional packages on a clean install of Ubuntu 14.04 LTS Desktop.

Went through the CMakeLists.txt files in the repo and added the following optional library dependencies - Snappy, Bzip2, Linux FUSE and Jansson.

Updated the required packages / version numbers from the trunk branch version of BUILDING.txt.

  • HADOOP-8989 Majorhadoop fs -find feature

New fs -find command

  • HDFS-7806 MinorRefactor: move StorageType from hadoop-hdfs to hadoop-common

This fix moves the public class StorageType from the package org.apache.hadoop.hdfs to org.apache.hadoop.fs.

  • HDFS-7774 CriticalUnresolved symbols error while compiling HDFS on Windows 7/32 bit

LibHDFS now supports 32-bit build targets on Windows.

  • HDFS-7584 MajorEnable Quota Support for Storage Types
  1. Introduced quota by storage type as a hard limit on the amount of space usage allowed for different storage types (SSD, DISK, ARCHIVE) under the target directory.
  2. Added {{SetQuotaByStorageType}} API and {{-storagetype}} option for {{hdfs dfsadmin -setSpaceQuota/-clrSpaceQuota}} commands to allow set/clear quota by storage type under the target directory.
  • HDFS-7411 MajorRefactor and improve decommissioning logic into DecommissionManager

This change introduces a new configuration key used to throttle decommissioning work, “dfs.namenode.decommission.blocks.per.interval”. This new key overrides and deprecates the previous related configuration key “dfs.namenode.decommission.nodes.per.interval”. The new key is intended to result in more predictable pause times while scanning decommissioning nodes.

  • HDFS-7270 MajorAdd congestion signaling capability to DataNode write protocol

Introduced a new configuration dfs.pipeline.ecn. When the configuration is turned on, DataNodes will signal in the writing pipelines when they are overloaded. The client can back off based on this congestion signal to avoid overloading the system.

  • HDFS-7210 MajorAvoid two separate RPC’s namenode.append() and namenode.getFileInfo() for an append call from DFSClient

WARNING: No release note provided for this incompatible change.

  • HDFS-6651 CriticalDeletion failure can leak inodes permanently

WARNING: No release note provided for this incompatible change.

  • HDFS-6252 MinorPhase out the old web UI in HDFS

WARNING: No release note provided for this incompatible change.

  • HDFS-6133 MajorAdd a feature for replica pinning so that a pinned replica will not be moved by Balancer/Mover.

Add a feature for replica pinning so that when a replica is pinned in a datanode, it will not be moved by Balancer/Mover. The replica pinning feature can be enabled/disabled by “dfs.datanode.block-pinning.enabled”, where the default is false.

  • HDFS-3689 MajorAdd support for variable length block
  1. HDFS now can choose to append data to a new block instead of end of the last partial block. Users can pass {{CreateFlag.APPEND}} and {{CreateFlag.NEW_BLOCK}} to the {{append}} API to indicate this requirement.
  2. HDFS now allows users to pass {{SyncFlag.END_BLOCK}} to the {{hsync}} API to finish the current block and write remaining data to a new block.
  • HDFS-1522 MajorMerge Block.BLOCK_FILE_PREFIX and DataStorage.BLOCK_FILE_PREFIX into one constant

This merges Block.BLOCK_FILE_PREFIX and DataStorage.BLOCK_FILE_PREFIX into one constant. Hard-coded literals of “blk_” in various files are also updated to use the same constant.

  • HDFS-1362 MajorProvide volume management functionality for DataNode

Based on the reconfiguration framework provided by HADOOP-7001, enable reconfigure the dfs.datanode.data.dir and add new volumes into service.

  • MAPREDUCE-5583 MajorAbility to limit running map and reduce tasks

This introduces two new MR2 job configs, mentioned below, which allow users to control the maximum simultaneously-running tasks of the submitted job, across the cluster:

  • mapreduce.job.running.map.limit (default: 0, for no limit)
  • mapreduce.job.running.reduce.limit (default: 0, for no limit)

This is controllable at a per-job level.

  • YARN-3217 MajorRemove httpclient dependency from hadoop-yarn-server-web-proxy

Hadoop 2.7 1 Winutils Exe Download 64-bit

Removed commons-httpclient dependency from hadoop-yarn-server-web-proxy module.

  • YARN-3154 BlockerShould not upload partial logs for MR jobs or other 'short-running’ applications

Applications which made use of the LogAggregationContext in their application will need to revisit this code in order to make sure that their logs continue to get rolled out.

Hadoop is released as source code tarballs with corresponding binary tarballs for convenience. The downloads are distributed via mirror sites and should be checked for tampering using GPG or SHA-512.
