> HADOOP-4491 fixed the secure permissions of local files on a TT. While
> testing HADOOP-4491 on a cluster, [~karams] found out a bug. All the
> files/dirs have should be owned by the group corresponding to the group owner
> of the task-controller binary (via using getegid()) which in turn is a
> special group to which *only* TT user belongs. HADOOP-4491 incorrectly set it
> to primary group of the TT via getgid(), and not the special group.
