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. -- This message was sent by Atlassian JIRA (v6.2#6252)
