-------------------------------------
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.
