[jira] [Updated] (HIVE-17921) Aggregation with struct in LLAP
produces wrong result
[ https://issues.apache.org/jira/browse/HIVE-17921?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Eugene Koifman updated HIVE-17921:
----------------------------------
Description:
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.
