dhruba borthakur commented on HDFS-1415:
----------------------------------------
Code looks good to me. I wonder why the HDFS namenode was not using the group
information in the first place, it seemed like a pretty reasonable thing to do.
Maybe Owen has some historical perspective on this?
Do we need to put some javadocs to state that if there are multiple groups in
the ugi, then the first one takes efffect as far as file permissions are
concerned?
Also, this looks like an incompatible change, especially because files will now
have the appropriate group information.

> In NameNode.create() and NameNode.mkdirs() do not pass the group name. So it
