------------------------------------

Hi all, please help me to know what I need to do to move on to have code review. As I mentioned
earlier, the failed test cases have no relation with the code change. Thanks.

> We need a plugin API to translate long principal names (e.g. john.doe@EXAMPLE.COM) to
local OS user names (e.g. user123456) arbitrarily.
> For some organizations the name translation is straightforward (e.g. john.doe@EXAMPLE.COM
to john_doe), and the hadoop.security.auth_to_local configurable mapping is sufficient to
resolve this (see HADOOP-6526). However, in some other cases the name translation is arbitrary
and cannot be generalized by a set of translation rules easily.
