Mohit Sabharwal commented on PIG-4542:
--------------------------------------
Thanks, [~kellyzly]
1) Fixed parent reference in SparkPlan physical operators.
2) You're right, POStreamSpark was handling (potentially multiple) last
buffered records, not necessarily 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.
