----------------------------------------
Although the patch solves the issue at hand, I will like to understand how the testcases, that all have unsecure setup, are passing without the patch. Kan, could you please dig a bit deeper and get the explanation. Thanks!

--------------------------------------
This patch has been manually verified. Simply bring up a jobtracker with security turned off and check it's up properly and no NPE is thrown.

Devaraj Das commented on MAPREDUCE-1992:
----------------------------------------
Okay. I have committed the fix to trunk (since the fix seems the right thing to do anyway) but please investigate why the unit tests didn't catch the problem earlier. I am not marking the issue "resolved" yet.

Kan Zhang commented on MAPREDUCE-1992:
--------------------------------------
Looks like I screwed it up when I ran tests for MAPREDUCE-1945, since the Hudson run for MAPREDUCE-1993 clearly caught this bug. I ran my local test again and caught it, too.

Kan Zhang commented on MAPREDUCE-1992:
--------------------------------------
I wonder about that, too. But I suggest we commit this patch now so that other people are unblocked. I'll take a look later on why existing unit tests didn't catch it and open a new jira if necessary.
