Sean Owen resolved SPARK-12162.
-------------------------------
Resolution: Not A Problem
I think the answer is that you can't in general "embed" the Spark executor
processes.
> Embedded Spark on JBoss server cause crashing due system.exit when
> SparkUncaughtExceptionHandler called

> Key: SPARK-12162
> URL: https://issues.apache.org/jira/browse/SPARK-12162
> Project: Spark
> Issue Type: Bug
> Reporter: Sasi
> Priority: Critical
>
> Hello,
> I'm running Spark on JBoss and some times i'm getting the following exception:
> {code}
> ERROR : (org.apache.spark.util.SparkUncaughtExceptionHandler:96)
> -[appclient-registration-retry-thread] Uncaught exception in thread
> Thread[appclient-registration-retry-thread,5,jboss]
> java.util.concurrent.RejectedExecutionException: Task
> java.util.concurrent.FutureTask@4e33f83e rejected from
> java.util.concurrent.ThreadPoolExecutor@35eed68e[Running, pool size = 1,
> active threads = 0, queued tasks = 0, completed tasks = 3]
> {code}
> Then my JBoss crashed, so I take a look on the source of
> SparkUncaughtExceptionHandler and I notes that when the exception called it
> do System.exit(SparkExitCode.UNCAUGHT_EXCEPTION).

> Since the System.exit(...) called then my JBoss crash.
> Any workaround/fix that can help me?
> Thanks,
> Sasi
