> Some Operators, such as MergeCogroup, Stream, CollectedGroup etc buffer some input records
to constitute the result tuples. The last result tuples are buffered in the operator.  These
Operators need a flag to indicate the end of input, so that they can flush and constitute
their last tuples.
> Currently, the flag 'parentPlan.endOfAllInput' is targeted for flushing the buffered
tuples in MR mode.  But it does not work with OutputConsumeIterator in Spark mode.
