Todd Lipcon commented on HDFS-2011:
-----------------------------------

re SecurityException: I still don't see any reason that delete() would throw 
such an exception. AFAIK that only happens if a security manager is installed, 
which we never expect in unit tests.

Will try to look over the new patch revision later today or early next week. 
Thanks!
