Harish Butani commented on HIVE-7724:
-------------------------------------
Decided to go with *Rewrite in Hive* option for now. To go the *Optiq
Decorrelation* route, need the enhancements planned in OPTIQ-373 around In/Not
In and Null values.
Patch attached. Review at https://reviews.apache.org/r/25010/
> CBO: support Subquery predicates
