Subject [jira] [Created] (HIVE-10160) Give a warning when grouping or ordering by a constant column
Date Tue, 31 Mar 2015 05:55:52 GMT
Lefty Leverenz created HIVE-10160:
-------------------------------------

             Summary: Give a warning when grouping or ordering by a constant column
                 Key: HIVE-10160
                 URL: https://issues.apache.org/jira/browse/HIVE-10160
             Project: Hive
          Issue Type: Improvement
          Components: Query Processor
            Reporter: Lefty Leverenz
            Priority: Minor


To avoid confusion, a warning should be issued when users specify column positions instead
of names in a GROUP BY or ORDER BY clause (unless hive.groupby.orderby.position.alias is set
to true in Hive 0.11.0 or later).
