Ravi Gummadi commented on MAPREDUCE-1085:
-----------------------------------------
I was looking at older branch. Code is different in trunk.
Fine. Trunk's code is checking for null in both cases of DefaultTaskController
and LinuxTaskController. So the code changes of the patch should be fine.
+1.
