-------------------------------------
Summary: Logic to disable SMB/BMJ on external tables is too strict
Key: HIVE-20017
URL: https://issues.apache.org/jira/browse/HIVE-20017
Project: Hive
Issue Type: Bug
Reporter: Deepak Jaiswal
Assignee: Deepak Jaiswal
The logic to disable SMB and BMJ on external tables is too strict as done in
JIRA,
https://issues.apache.org/jira/browse/HIVE-19336
For SMB, if there is a group by, then the source table becomes irrelevant as
the rows are bucketed and sorted by group by keys.
For BMJ, the small table(s) can be external, the check needs to be done only
for big table.
