Key: HIVE-6753
URL: https://issues.apache.org/jira/browse/HIVE-6753
Project: Hive
Issue Type: Bug
Reporter: Gunther Hagleitner
Assignee: Gunther Hagleitner
In some cases when there's a mapjoin in union work we need to broadcast the
same result set to multiple downstream work items. This causes a vertex failure
right now.
