[jira] [Commented] (HIVE-17921) Aggregation with struct in LLAP produces wrong result

["Saurabh Seth (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HIVE-17921?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16601923#comment-16601923 ] 

Saurabh Seth commented on HIVE-17921:
-------------------------------------

I also updated llap/acid_vectorization_original.q.out which now doesn't have the extra row:

-NULL 6

In addition, the masked patterns seem to have changed since the test results were last updated. I have updated those as well so that this test passes.

> Consider 
> {noformat}
> select ROW__ID, count(*) from over10k_orc_bucketed group by ROW__ID having count(*) > 1;
> {noformat}
>  in acid_vectorization_original.q (available since HIVE-17458)
> when run using TestMiniLlapCliDriver produces "NULL, N" where N varies from run to run.
> The right answer is empty results set as can be seen by running
> {noformat}
> select ROW__ID, * from over10k_orc_bucketed where ROW__ID is null
> {noformat}
> in the same test.
> This is with 
> {noformat}
> set hive.vectorized.execution.enabled=true;
> set hive.vectorized.row.identifier.enabled=true;
> {noformat}
> It fails with TestMiniLlapCliDriver but not TestMiniTezCliDriver.  See acid_vectorization_original_tez.q which has identical query.
