             Summary: Release RDD cache when Hive query is done [Spark Branch]
                 Key: HIVE-8843
                 URL: https://issues.apache.org/jira/browse/HIVE-8843
             Project: Hive
          Issue Type: Sub-task
          Components: Spark
            Reporter: Xuefu Zhang


In some multi-inser cases, RDD.cache() is called to improve performance. RDD is 
SparkContext specific, but the caching is useful only for the query. Thus, once 
the query is executed, we need to release the cache used by calling 
RDD.uncache().
