Jitendra Nath Pandey commented on HADOOP-7853:
----------------------------------------------
I agree to the approach taken in the patch. Some comments
1) Please wrap the LOG.debug statements with isLogDebugEnabled.
2) Indentation of logPriviledgedAction.
3) Change to SecurityUtil.java doesn't seem required.
4) DummyLoginConfiguration is a good idea. Please clarify in the comment that
it is there to ensure that statically configured one is not used.
