Remus Rusanu updated HIVE-4612:
-------------------------------
Fix Version/s: vectorization-branch
Status: Patch Available (was: Open)
Fix provided for int key column. I'm convinced the same problem exists for all
other type that differ from the supported vectorized types. Will need to
revisit. I propose to address that, along with other issues, in HIVE-4604
> Vectorized aggregates do not emit proper rows in presence of GROUP BY

> I discovered this while testing the fix for HIVE-4451 and HIVE-4452. The VGBy
> is emitting appropriate number of rows, but the row-mode ReduceSinkOperatoir
> only logs one row and the final result is incomplete. Investigating. Related
> to HIVE-4599.
