Eugene Koifman commented on HIVE-17921: --------------------------------------- I also have "select ROW__ID from T group by ROW__ID having count(*) > 1" in TestTxnNoBuckets.testInsertFromUnion() which runs MR - works OK > 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 > Priority: Blocker > > 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. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
