Venki Korukanti commented on HIVE-7492:
---------------------------------------
GroupBy operator is adding output records to Output Collector after closing the
ExecMapper/ExecReducer. Need to check if {{lastRecordOutput}} has any records
after closing the ExecMapper/ExecReducer. I will log a JIRA and attach the
patch.

> SparkCollector is used to collect the rows generated by HiveMapFunction or
> HiveReduceFunction. It currently is backed by a ArrayList, and thus has
> unbounded memory usage. Ideally, the collector should have a bounded memory
> usage, and be able to spill to disc when its quota is reached.
