Possible NPE in org.apache.hadoop.mapred.MapTask.MapOutputBuffer.collect(K key, V value, int
partition)
-------------------------------------------------------------------------------------------------------

                 Key: MAPREDUCE-3516
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-3516
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: mrv2
    Affects Versions: 0.23.0, 0.20.205.0, 0.20.203.0, 0.20.2, 0.20.1

            Assignee: Subroto Sanyal


*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.
