[jira] [Created] (HIVE-8274) Refactoring SparkPlan and SparkPlanGeneration [Spark Branch]

Xuefu Zhang created HIVE-8274:
---------------------------------

             Summary: Refactoring SparkPlan and SparkPlanGeneration [Spark Branch]
                 Key: HIVE-8274
                 URL: https://issues.apache.org/jira/browse/HIVE-8274
             Project: Hive
          Issue Type: Task
          Components: Spark
            Reporter: Xuefu Zhang
            Assignee: Xuefu Zhang


As part of HIVE-8118, SparkWork will be modified with cloned Map/Reduce- Works, and input RDDs and some intemediate RDDs may need to be cached for performance. To accomodate these, SparkPlan model and SparkPlan generation need to be refactored.
