Craig Macdonald commented on HADOOP-4104:
-----------------------------------------

Yes, I agree. Hadoop doesnt have a authentication system, so we shouldn't force 
one on it in this patch. 

+1 on HADOOP-4104.2.txt: I have read through the code and am happy with the 
patch.

@ Sameer - I agree that libhdfs can leverage any additional authentication 
functionality. I should just make clear that a requirement of any 
authentication change should be "impersonation" by a process running with 
superuser privileges, as provided hdfsConnectAsUser().

> add time, permission and user attribute support to libhdfs
