[jira] [Commented] (HIVE-4612) Vectorized aggregates do not emit
proper rows in presence of GROUP BY
[ https://issues.apache.org/jira/browse/HIVE-4612?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13673403#comment-13673403 ]
Ashutosh Chauhan commented on HIVE-4612:
----------------------------------------
Not specific to this patch, but VectorHashKeyWrapperBatch.java should be in vector package (instead of exec). Can you file a follow-up jira to move that file?

> 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.
