-------------------------------------
Summary: cbo_gby q test fails with a client exception if
bucketmapjoin is enabled
Key: HIVE-11924
URL: https://issues.apache.org/jira/browse/HIVE-11924
Project: Hive
Issue Type: Bug
Affects Versions: 1.2.1, 2.0.0
Reporter: Siddharth Seth
Priority: Critical
Affects branch-1 and the llap branch. Not sure how far back this goes.
Steps to reproduce.
Option1:
1. Apply patch from HIVE-11923.
2. Run all tez / llap tests or the following q files
(-Dqfile=auto_sortmerge_join_9.q,cbo_gby.q)
Sequence is important.
Option2:
1. Modify cbo_gby.q to set the following
{code}
set hive.optimize.bucketmapjoin=true;
set hive.optimize.bucketmapjoin.sortedmerge=true;
set hive.auto.convert.sortmerge.join=true;
set hive.auto.convert.sortmerge.join.to.mapjoin=false;
{code}
2. Run only the cbo_gby.q with tez or llap
Fails with the following exception in the client

Overall looks like this is something that could be hit during regular usage as
well.
