----------------------------------------
Summary: Joining multiple union all outputs fails on Tez
Key: HIVE-6611
URL: https://issues.apache.org/jira/browse/HIVE-6611
Project: Hive
Issue Type: Bug
Reporter: Gunther Hagleitner
Assignee: Gunther Hagleitner
Priority: Critical
Queries like:
with u as (select * from src union all select * from src)
select * from u join u;
will fail on Tez because only one union flows into the join reduce phase.
