Harsh J commented on MAPREDUCE-3516:
------------------------------------

Doesn't this fall under the user-error land? Is this open to add-on guards that catch NPEs and throw up appropriate messages? I'm fine with that -- just asking if that is the goal of this JIRA.

> *org.apache.hadoop.mapred.MapTask.MapOutputBuffer.collect* accepts a pair of Key and Value. There is chance that if somehow if a Null value or Key is passed to the method, we can end up having NPE.
