Todd Lipcon commented on HDFS-1322:
-----------------------------------
Shouldn't we update the javadoc to be clearer, as Ravi mentioned?
> DistributedFileSystem.mkdirs(dir, dirPermission) doesn't set the permissions
> of created dir to dirPermission

> 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.
