Review request for hive and Ashutosh Chauhan.


Changes
-------

  


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.
