[jira] [Commented] (SPARK-16522) [MESOS] Spark application throws
exception on exit
[ https://issues.apache.org/jira/browse/SPARK-16522?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15409502#comment-15409502 ]
Laurent Hoss commented on SPARK-16522:
--------------------------------------
Is this gonna be fixed soon (2.0.1) ?!
I just got a stacktrace of a developer here, who's job *failed* .. with following exception

> Applications' result is not affected by this error.
> This issue can be simply reproduced by launching a spark-shell, and exit after running the following commands:
> {code}
> val rdd = sc.parallelize(1 to 10, 10)
> rdd.map { _ + 1} collect
> {code}
> The root cause is that in SparkContext.stop(), MesosCoarseGrainedSchedulerBackend.stop() calls CoarseGrainedSchedulerBackend.stop(). The latter sends messages to stop executors and also stop the driver endpoint without waiting for the actual stop of executors. MesosCoarseGrainedSchedulerBackend.stop() still waits for the executors to stop in a timeout. During the wait, MesosCoarseGrainedSchedulerBackend.statusUpdate() generally will be called to update executors' status, and in turn removeExecutor() is called. But at that time, the driver endpoint is not available.
