Saurabh Seth commented on HIVE-17921:
-------------------------------------
The test failures are unrelated to this patch. This patch fixes an existing
test result so I haven't added any more tests.
> Aggregation with struct in LLAP produces wrong result

> Key: HIVE-17921
> URL: https://issues.apache.org/jira/browse/HIVE-17921
> Project: Hive
> Issue Type: Sub-task
> Components: llap, Transactions
> Affects Versions: 3.0.0
> Reporter: Eugene Koifman
> Assignee: Saurabh Seth
> Priority: Blocker
> Attachments: HIVE-17921.2.patch, HIVE-17921.patch

> 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.
