-----------------------------------
Summary: Bucket map join optimization not applied to left semi join
Key: HIVE-3765
URL: https://issues.apache.org/jira/browse/HIVE-3765
Project: Hive
Issue Type: Bug
Affects Versions: 0.11
Reporter: Kevin Wilfong
Assignee: Kevin Wilfong
When all the hints and settings are present to use the bucket map join
optimization, it will not get applied if the join is a left semi join. It
works for left outer joins, so it seems it should work for left semi joins.
