> 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.
