Jesus Camacho Rodriguez commented on HIVE-15994:
------------------------------------------------
[~ashutoshc], can you take a look? This is an issue that is happening when
grouping function is used with plain group by (a case that is trivial but
apparently valid, and that was not covered in the original implementation).
Thanks
