Hadoop is based on Apache Hadoop 1.2.0 and includes the following additional patches:
HDFS-7503: Namenode restart after large deletions can cause slow processReport (due to logging)
HDFS-6822: In branch-1, Namenode and datanode fails to replace "_HOST" to hostname for hadoop.http.authentication.kerberos.principal
HDFS-6277: WebHdfsFileSystem#toUrl does not perform character escaping for rename
HDFS-5306: Datanode https port is not available at the namenode
HDFS-3794: WebHDFS: openFileWithOffset returns premature end of content-length delimited message body
HDFS-5306: Datanode https port is not available at the namenode
HDFS-6822 Namenode and datanode fails to replace "_HOST" to hostname for hadoop.http.authentication.kerberos.principal
HDFS-6141: WebHdfsFileSystem#toUrl does not perform character escaping.
HDFS-5982: Need to update snapshot manager when applying editlog for deleting a snapshottable directory
HDFS-2264: NamenodeProtocol has the wrong value for clientPrincipal in KerberosInfo annotation
HDFS-3404: Make putImage in GetImageServlet infer remote address to fetch from request
HADOOP-10627: Add documentation for http/https policy configuration/setup
HADOOP-9509: Implemented

DFSClient#getNamenode()
FileStatus#isDirectory()
HDFS-4880: Added support to print image and edits file loaded by the NameNode, in the logs.
HDFS-4944: Fixed file path issue with WebHDFS. WebHDFS can now create a file path containing characters that must be URI-encoded (such as space).
HDFS Snapshot related changes:
HDFS-4842: Added ability to identify correct prior snapshot before deleting a snapshot under a renamed subtree.
HDFS-4857: Enhanced
Snapshot.Root
andAbstractINodeDiff#snapshotINode
. (Snapshot.Root
andAbstractINodeDiff#snapshotINode
should not be put intoINodeMap
when loadingFSImage
.)HDFS-4863: The
root
directory can now be added to thesnapshottable
directory list while loadingfsimage
.HDFS-4846: Enhanced snapshot command line (CLI) commands output stacktrace for invalid arguments.
HDFS-4848: Fixed

.DFSClient.getSnapshotDiffReport
now usesstring
path instead of using theo.a.h.fs.Path
.HDFS-4875: Added support for testing snapshot file length.
HDFS-5005: Moved
SnapshotException
andSnapshotAccessControlException
too.a.h.hdfs.protocol
.
HDFS-2802: Added support for RW/RO snapshots in HDFS.
HDFS-4750: Added support for NFSv3 interface to HDFS.
MAPREDUCE-4366 Back port MAPREDUCE-4366 to Hadoop 1.2
MAPREDUCE-4661: Backport HTTPS to WebUIs to branch-1.
MAPREDUCE-5109: Added support to apply
Job view-acl
to job lists on JobTracker and also to the JobHistory listings.MAPREDUCE-5217: Fixed issues for
DistCP
when launched by Oozie on a secure cluster.MAPREDUCE-5256: Improved
CombineInputFormat
to make it thread safe. This issue was affecting HiveServer.MAPREDUCE-5408: Backport MAPREDUCE-336 to branch-1.
HDFS-4334: Added support to enable adding a unique id to each INode.
HDFS-4635: Move
BlockManager#computeCapacity
toLightWeightGSet
.HDFS-4434: Added support for inode ID to inode map.
HDFS-4785: Fixed issue for Concat operation that affected removal of the concatenated files from InodeMap.
HDFS-4784: Fixed Null Pointer Exception (NPE) in

.HADOOP-8923: Fixed incorect rendering of the intermediate web user interface page caused when the authentication cookie (SPENGO/custom) expires.
