------------------------------------

             Summary: Combine equavilent leaf works in SparkWork[Spark Branch]
                 Key: HIVE-11267
                 URL: https://issues.apache.org/jira/browse/HIVE-11267
             Project: Hive
          Issue Type: Sub-task
          Components: Spark
            Reporter: Chengxiang Li
            Assignee: Chengxiang Li
            Priority: Minor


There could be multi leaf works in SparkWork, like self-union query. If the subqueries are
same with each other, we may combine the subqueries, and just execute once, then fetch twice
in FetchTask.
