>  When we are limiting on unsorted output, we can stop after reaching the count in the Processor. But if limiting has to be done on sorted output in map phase it is not possible as sorting is done by OnFileSortedOutput. If limiting was supported as part of the output, then we can limit records before writing to each part file after Partitioner is applied.
