Review request for hive and Ashutosh Chauhan.
Bugs: HIVE-4965
https://issues.apache.org/jira/browse/HIVE-4965
Repository: hive-git
Description
-------
There is no need to create an output PTF Partition for the last PTF in a chain.
For the Windowing PTF this should give a perf. boost; we avoid creating
temporary results for each UDAF; avoid populating an output Partition.
