Yi Liu updated HADOOP-10520:
----------------------------

    Attachment: HADOOP-10520.1.patch

Thanks Uma and Alejandro for review. I have updated according to your comments. Right now
we support setting/removing single xattr and it can cover most use cases and can be extended
in future. The xattr name must be prefixed with user/trusted/security/system. For more detail,
please refer to the attached patch.
