> MapOutputTrackerMaster.shufflestatuses can be mistakenly cleaned by Shuffle
> Cleanup feature, leading to SparkException (crashing the SparkContext) by the
> subsequent access to that already removed shuffle metadata. A real case
> (limited to local cluster currently) is the ongoing subquery could access the
> shuffle metadata which has been already cleanedup after the main query
> completes. See the detailed discussion at:
