-* [HADOOP-7229](https://issues.apache.org/jira/browse/HADOOP-7229) | *Major* | **Absolute path to kinit in auto-renewal thread**
+* [HADOOP-6344](https://issues.apache.org/jira/browse/HADOOP-6344) | *Major* | **rm and rmr fail to correctly move the user's files to the trash prior to deleting when they are over quota.**
 
-When Hadoop's Kerberos integration is enabled, it is now required that either {{kinit}} be on the path for user accounts running the Hadoop client, or that the {{hadoop.kerberos.kinit.command}} configuration option be manually set to the absolute path to {{kinit}}.
+Trash feature notifies user of over-quota condition rather than silently deleting files/directories; deletion can be compelled with "rm -skiptrash".

-* [HADOOP-6949](https://issues.apache.org/jira/browse/HADOOP-6949) | *Major* | **Reduces RPC packet size for primitive arrays, especially long[], which is used at block reporting**
+* [HDFS-708](https://issues.apache.org/jira/browse/HDFS-708) | *Major* | **A stress-test tool for HDFS.**
 
-Increments the RPC protocol version in org.apache.hadoop.ipc.Server from 4 to 5.
-Introduces ArrayPrimitiveWritable for a much more efficient wire format to transmit arrays of primitives over RPC. ObjectWritable uses the new writable for array of primitives for RPC and continues to use existing format for on-disk data.
+Does not currently provide anything but uniform distribution.
+Uses some older depreciated class interfaces (for mapper and reducer)
+This was tested on 0.20 and 0.22 (locally) so it should be fairly backwards compatible.

+* Removed the configuration property mapreduce.cluster.job-authorization-enabled.
+* Added mapreduce.cluster.acls.enabled as the single configuration property in mapred-default.xml that enables the authorization checks for all job level and queue level operations.
+* To enable authorization of users to do job level and queue level operations, mapreduce.cluster.acls.enabled is to be set to true in JobTracker's configuration and in all TaskTrackers' configurations.
+* To get access to a job, it is enough for a user to be part of one of the access lists i.e. either job-acl or queue-admins-acl(unlike before, when, one has to be part of both the lists).
+* Queue administrators(configured via acl-administer-jobs) of a queue can do all view-job and modify-job operations on all jobs submitted to that queue.
+* ClusterOwner(who started the mapreduce cluster) and cluster administrators(configured via mapreduce.cluster.permissions.supergroup) can do all job level operations and queue level operations on all jobs on all queues in that cluster irrespective of job-acls and queue-acls configured.
+* JobOwner(who submitted job to a queue) can do all view-job and modify-job operations on his/her job irrespective of job-acls and queue-acls.
+* Since aclsEnabled flag is removed from queues configuration files, "refresh of queues configuration" will not change mapreduce.cluster.acls.enabled on the fly. mapreduce.cluster.acls.enabled can be modified only when restarting the mapreduce cluster.

-* Removed aclsEnabled flag from queues configuration files.
-* Removed the configuration property mapreduce.cluster.job-authorization-enabled.
-* Added mapreduce.cluster.acls.enabled as the single configuration property in mapred-default.xml that enables the authorization checks for all job level and queue level operations.
-* To enable authorization of users to do job level and queue level operations, mapreduce.cluster.acls.enabled is to be set to true in JobTracker's configuration and in all TaskTrackers' configurations.
-* To get access to a job, it is enough for a user to be part of one of the access lists i.e. either job-acl or queue-admins-acl(unlike before, when, one has to be part of both the lists).
-* Queue administrators(configured via acl-administer-jobs) of a queue can do all view-job and modify-job operations on all jobs submitted to that queue. 
-* ClusterOwner(who started the mapreduce cluster) and cluster administrators(configured via mapreduce.cluster.permissions.supergroup) can do all job level operations and queue level operations on all jobs on all queues in that cluster irrespective of job-acls and queue-acls configured.
-* JobOwner(who submitted job to a queue) can do all view-job and modify-job operations on his/her job irrespective of job-acls and queue-acls.
-* Since aclsEnabled flag is removed from queues configuration files, "refresh of queues configuration" will not change mapreduce.cluster.acls.enabled on the fly. mapreduce.cluster.acls.enabled can be modified only when restarting the mapreduce cluster.

-this setting points to the server principal for RefreshUserToGroupMappingsProtocol.
-The value should be either NN or JT principal depending if it is used in DFAdmin or MRAdmin. The value is set by the application. No need for default value.
+Increments the RPC protocol version in org.apache.hadoop.ipc.Server from 4 to 5.
+Introduces ArrayPrimitiveWritable for a much more efficient wire format to transmit arrays of primitives over RPC. ObjectWritable uses the new writable for array of primitives for RPC and continues to use existing format for on-disk data.
