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

             Summary: Modify SparkPlan generation to set toCache flag to SparkTrans where
caching is needed [Spark Branch]
                 Key: HIVE-8437
                 URL: https://issues.apache.org/jira/browse/HIVE-8437
             Project: Hive
          Issue Type: Sub-task
          Components: Spark
            Reporter: Xuefu Zhang


HIVE-8436 may modify the SparkWork right before SparkPlan generation. When this happens, the
output from some SparkTrans needs to be cached to avoid regenerating the RDD. For more information,
please refer to the design doc.
