evaluation of THEN/ELSE
                 Key: HIVE-18819
                 URL: https://issues.apache.org/jira/browse/HIVE-18819

    Affects Versions: 3.0.0
            Reporter: Matt McCline

Currently, all the rows of a batch are evaluated for the THEN and ELSE 
expressions even though only a value from one of them is needed for any 
particular row.
