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)
