> Issue Type: Sub-task
> Components: Spark
> Affects Versions: spark-branch

> Currently, HIVE-8622 is implemented based on an assumption, that for a map
> join query, a BaseWork would not have multiple children. By testing through
> subquery_multiinsert.q did reveal that's the case. But, we need to
> investigate on this, and make sure this won't happen in general.
