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

Eugene Koifman created HIVE-17921:
-------------------------------------

             Summary: 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


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.
