> 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.
