Vineet Garg commented on HIVE-12301:
------------------------------------
I am working on HIVE-14396 which is running into similar issue. It looks like
that this fix wasn't completely correct. I have a reproducer which I believe
will reproduce what is incorrect with the fix. But that reproducer has also
exposed another wrong result issue which needs to be fixed first.
