Kihwal Lee commented on HADOOP-9352:
------------------------------------

+1 Risk seems minimal. It's still marked as limited private, so I hope most users won't depend
on it.

> The {{UGI.setLoginUser}} method is not publicly exposed, which makes it impossible to
correctly test code executed outside of an explicit {{doAs}}.  {{getCurrentUser}}/{{getLoginUser}}
will always vivify the login user from the user running the test, and not an arbitrary user
to be determined by the test.  The method is documented with why it's not ready for prime-time,
but it's good enough for tests.
