Vinod Kumar Vavilapalli resolved MAPREDUCE-3628.
------------------------------------------------

       Resolution: Fixed
    Fix Version/s:     (was: 0.23.1)

Thanks for the update Amol. 4% is fair, we can look at it in the next iteration.

In all likelihood, this got resolved after HDFS-2923. Closing this as fixed.
