[jira] [Created] (HIVE-8841) Make RDD caching work for multi-insert after HIVE-8793 when map join is involved [Spark Branch]

             Summary: Make RDD caching work for multi-insert after HIVE-8793 when map join is involved [Spark Branch]
                 Key: HIVE-8841
                 URL: https://issues.apache.org/jira/browse/HIVE-8841
             Project: Hive
          Issue Type: Sub-task
          Components: Spark
            Reporter: Xuefu Zhang


Splitting SparkWork now happens before MapJoinResolver. As MapJoinResolve may further spins off a dependent SparkWork for small tables of a join, we need to make Spark RDD caching continue work even across SparkWorks.
