Suresh Srinivas commented on HADOOP-6731:
-----------------------------------------
On HDFS we do not support set-user-ID-on-execution-bit. On linux all the
following is support for chmod:
7, 77, 777, 1777. Should we make chmod parser also consistent with this? I feel
we should either change both creation umask and chmod umask or leave both of
them as it is. Any thoughts?
> Octal umask with less than 3 digits is not handled
