Harish Butani commented on HIVE-4904:
-------------------------------------
Rebased earlier patch.
- Some of the changes to SemAly already went in, probably in HIVE-4293
- added couple of more checks:
- When pruning the RedSink signature create a new ArrayList. The issue was
the ArrayList in the RowSchema was being shared with the
RowSchema of the ParentOp.
- When there are distinct aggregations, the resolution back from GBy to
RedSink outputCols is not working. For now I have added a check that adds all
Value
Cols of the RedSink to the prunedList of the RedSink
Still need to add the test from HIVE-6912.
> A little more CP crossing RS boundaries
