> CopyUtils currently invokes distcp on whether "hive.exec.copyfile.maxnumfiles" or "hive.exec.copyfile.maxsize" condition is breached,  should only be invoked when both are breached so should be AND rather than OR. 
> distcp cannot do a distributed copy of a large single file hence more reason to do the above change.
