---------------------------------
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().
