             Summary: add hints for semijoin reduction
                 Key: HIVE-16289
                 URL: https://issues.apache.org/jira/browse/HIVE-16289
             Project: Hive
          Issue Type: Bug
            Reporter: Sergey Shelukhin
            Assignee: Sergey Shelukhin


For now hints will only impact bloom filter size if semijoin is enabled.
In a follow-up, after some cost-based semi-join decision logic is added, they 
may also influence it.
