> Key: HIVE-20017
> URL: https://issues.apache.org/jira/browse/HIVE-20017
> Project: Hive
> Issue Type: Bug
> Reporter: Deepak Jaiswal
> Assignee: Deepak Jaiswal
> Priority: Major
>
> 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.
