Aihua Xu updated HIVE-13453:
----------------------------
Attachment: HIVE-13453.2.patch
Patch-2: Many test case failures were caused by the changing of inputOI =>
outputOI in merge function. Changed back to inputOI since the intermediate type
matches inputOI, not outputOI.
> Support ORDER BY and windowing clause in partitioning clause with distinct
> function
