Vectorized aggregates do not emit proper rows in presence of GROUP BY

    Details

      Description

      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.
