Ravi Phulari commented on HADOOP-6701:
--------------------------------------
This fix will change the way {{ch(mod/own/grp)}} returns exit codes.
Failure to execute chmod, chown, chgrp commands will return non zero exit code
with an error message.
> Incorrect exit codes for "dfs -chown", "dfs -chgrp"
