Phabricator updated HIVE-4965:
------------------------------

    Attachment: HIVE-4965.D12033.1.patch

hbutani requested code review of "HIVE-4965 [jira] Add support so that PTFs can stream their
output; Windowing PTF should do this".

Reviewers: JIRA, ashutoshc

fix lint issues

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.
