---------------------------------
Summary: Research to find out if it's possible to submit Spark
jobs concurrently using shared SparkContext
Key: HIVE-7525
URL: https://issues.apache.org/jira/browse/HIVE-7525
Project: Hive
Issue Type: Task
Components: Spark
Reporter: Xuefu Zhang
Assignee: Chao
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.
