> ----------------------------------------------------------------------
>
> Key: HIVE-18201
> URL: https://issues.apache.org/jira/browse/HIVE-18201
> Project: Hive
> Issue Type: Bug
> Affects Versions: 3.0.0
> Reporter: Nita Dembla
> Assignee: Ashutosh Chauhan
> Attachments: HIVE-18201.1.patch, query6.explain2.out
>
>
> sq_count_check() will either return an error at runtime or a single row. In
> case of query6, the subquery has avg() function that should return a single
> row. Attaching the explain.
> This does not need an x-prod, because it is not useful to shuffle the big
> table side for a cross-product against 1 row.
