John Vines commented on SPARK-12650:
------------------------------------

I'm launching the spark job from inside an App Master, as I said in my background.

>                 URL: https://issues.apache.org/jira/browse/SPARK-12650
>             Project: Spark
>          Issue Type: Bug
>          Components: Spark Submit
>    Affects Versions: 1.5.2
>         Environment: Hadoop 2.6.0
>            Reporter: John Vines

> Background-
> I have an app master designed to do some work and then launch a spark job.
> Issue-
> If I use yarn-cluster, then the SparkSubmit does not Xmx itself at all, leading to the
jvm taking a default heap which is relatively large. This causes a large amount of vmem to
be taken, so that it is killed by yarn. This can be worked around by disabling Yarn's vmem
check, but that is a hack.
> If I run it in yarn-client mode, it's fine as long as my container has enough space for
the driver, which is manageable. But I feel that the utter lack of Xmx settings for what I
believe is a very small jvm is a problem.
> I believe this was introduced with the fix for SPARK-3884
