Daryn Sharp commented on HADOOP-10475:
--------------------------------------
While the patch in this jira looks ok, I haven't had to chance to see if my
HADOOP-8726 was truly reverted.
At any rate, _please don't file and resolve security related tickets within
~6h_ - let alone contemplate reverting jiras w/o input from the assignee. I
have had to fix many delicate issues over the years and can state from personal
experience that small changes can cause subtle bugs.
