DistributedFileSystem.mkdirs(dir, dirPermission) doesn't set the permissions of created dir to dirPermission
------------------------------------------------------------------------------------------------------------

Key: HDFS-1322
URL: https://issues.apache.org/jira/browse/HDFS-1322
Project: Hadoop HDFS
Issue Type: Bug
Reporter: Ravi Gummadi


DistributedFileSystem.mkdirs(dir, dirPermission) calls DFSClient.mkdirs(dir, dirPermission) to create directory and then set permissions to (dirPermission & umask). Is this the intended behaviour ? I expect it to set permissions of dir to dirPermission instead of doing an AND with umask ---- similar to what 'chmod -m mode' does.

The javadoc of DFSClient.mkdirs() says that the permissions of created dir will be set to dirPermission, which is not done currently. This needs to be modified based on the actual behaviour.

This is not an issue in RawLocalFileSystem.
