             Summary: Support multi edge between nodes in SparkPlan[Spark Branch]
                 Key: HIVE-11082
                 URL: https://issues.apache.org/jira/browse/HIVE-11082
             Project: Hive
          Issue Type: Sub-task
          Components: Spark
            Reporter: Chengxiang Li


For Dynamic RDD caching optimization, we found SparkPlan::connect throw exception while we try to combine 2 works with same child, support multi edge between nodes in SparkPlan would help to enable dynamic RDD caching in more use cases, like self join and self union.
