Review comment:
I followed the same semantics as DistCp, DistCp also does removeAcl
first, added as part of HADOOP-16032.
The reason being if the directory at the target has ACCESS scope ACL and
the directory at source has only Default ACL, so setAcl will not remove the
ACCESS scope ACL, hence the ACL's on source & dest won't be same. So, to
counter that removeACl is called first.
