---------------------------------------
Thanks [~mohitsabharwal]:
the questions i don't understand from your patch and comment are:
1. poCollectedGroup.getPlans().get(0) equals poCollectedGroup.parentPlan? (see
review board)
2. {quote}
Deletes POStreamSpark since it was just handling the last record.
{quote}
can you explain why POStreamSpark handles the last record?
> OutputConsumerIterator should flush buffered records

>
> Certain operators may buffer the output. We need to flush the last set of
> records from such operators, when we encounter the last input record, before
> calling getNextTuple() for the last time.
> Currently, to flush the last set of records, we compute RDD.count() and
> compare the count with a running counter to determine if we have reached the
> last record. This is an unnecessary and inefficient.
