Yi Liu commented on HDFS-6374:
------------------------------

Thanks Charles for the patch.
Agree with Andrew, maybe we can add permission test in {{TestDFSShell}}, we already have some for xattr in that class.

> From the attr(5) manpage:
> {noformat}
>        For  this reason, extended user attributes are only allowed for regular
>        files and directories,  and  access  to  extended  user  attributes  is
>        restricted  to the owner and to users with appropriate capabilities for
>        directories with the sticky bit set (see the chmod(1) manual  page  for
>        an explanation of Sticky Directories).
> {noformat}
