Subject [jira] [Commented] (HIVE-4612) Vectorized aggregates do not emit proper rows in presence of GROUP BY
Date Mon, 03 Jun 2013 18:29:20 GMT

    [ 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.
