             Summary: Avoid redundant clone of JobConf
                 Key: HIVE-9216
                 URL: https://issues.apache.org/jira/browse/HIVE-9216
             Project: Hive
          Issue Type: Sub-task
          Components: Spark
            Reporter: Rui Li
            Assignee: Rui Li


Currently in SparkPlanGenerator, we clone job conf twice for each MapWork. 
Should avoid this as cloning job conf involves writing to HDFS.
