Subject [jira] [Commented] (HIVE-7724) CBO: support Subquery predicates
Date Sat, 23 Aug 2014 16:28:10 GMT

    [ https://issues.apache.org/jira/browse/HIVE-7724?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14108047#comment-14108047
] 

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/
