> Because CLI is using CommandWithDestination.java which add "._COPYING_" to the tail of
file name when it does the copy. It will cause problem if there is a file/dir already called
*._COPYING_ on HDFS.

> -bash-4.1$ hadoop fs -put 5M /user/occ/
> -bash-4.1$ hadoop fs -mv /user/occ/5M /user/occ/5M._COPYING_
> -bash-4.1$ hadoop fs -ls /user/occ/
