Date Wed, 05 Aug 2015 20:28:04 GMT
Sergey Shelukhin created HIVE-11471:
---------------------------------------

             Summary: Expose query cost estimates (from CBO?) in explain plan
                 Key: HIVE-11471
                 URL: https://issues.apache.org/jira/browse/HIVE-11471
             Project: Hive
          Issue Type: Bug
            Reporter: Sergey Shelukhin


Some users of Hive suggested that it would be useful to see abstract cost of the query plan
in explain, so that different manual rewrites of the query could be compared before running.
