      Description

      Refer to HIVE-7503 and SPARK-2688. Find out if it's possible to submit multiple spark jobs concurrently using a shared SparkContext. SparkClient's code can be manipulated for this test. Here is the process:

      1. Transform rdd1 to rdd2 using some transformation.
      2. call rdd2.cache() to persist it in memory.
      3. in two threads, calling accordingly:
      Thread a. rdd2 -> rdd3; rdd3.foreach()
      Thread b. rdd2 -> rdd4; rdd4.foreach()

      It would be nice to find out monitoring and error reporting aspects.
