-----------------------------------
Thanks a lot for reviewing it. Good point. Yes, it is a little intrusive for
the RSC one. Let me fix it.
> Release RDD cache when Hive query is done [Spark Branch]

> 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().
