Stavros Kontopoulos commented on SPARK-24641:
---------------------------------------------
[~igor.berman] The current idea of the shuffle service on mesos is to run it on
all slaves upfront with a constraint: {{"constraints": [["hostname",
"UNIQUE"]]}}.
So let's remove the case of "marathon haven't provisioned yet the external
shuffle service on particular node", because if that holds then that is not
going to work by design.
Now in case the shuffle service is available but due to network issues there is
a communication error then the executor mesos task should be non reachable as
well.
I can think of a case though where the shuffle service may fail and mesos
executor has started fine. In that case we could tell the executor to fail and
so the task can be restarted
elsewhere. Right now when an executor is started and we get a mesos task udpate
we try to connect to the shuffle service. If that fails then we do nothing. So
we should probably
improve the logic there. But first let's identify what should work and what
shouldn't.
Btw there is an ongoing effort to re-design the shuffle service to be based on
some storage and run as a service so things will get improved at some time.

> Spark-Mesos integration doesn't respect request to abort itself

> Key: SPARK-24641
> URL: https://issues.apache.org/jira/browse/SPARK-24641
> Project: Spark
> Issue Type: Bug
> Components: Mesos, Shuffle
> Affects Versions: 2.2.0
> Reporter: Igor Berman
> Priority: Major
>
> Hi,
> lately we came across following corner scenario:
> We are using dynamic allocation with external shuffle service that is managed
> by marathon.
>
> Due to some network/operation issue, the external shuffle service on one of
> the machines(mesos-slaves) is not available for few seconds(e.g. marathon
> haven't provisioned yet the external shuffle service on particular node, but
> framework itself already accepted offer on this node and tries to startup
> executor)
>
> This makes framework(spark driver) to fail and I see error from stderr of
> driver(seems like mesos-agent asks driver to abort itself), however spark
> context continues to run(seems like in kind of zombi mode, since it can't
> release resources to cluster and can't get additional offers since the
> framework is aborted from mesos perspective)
>
> The framework in mesos UI move to "inactive" state.
> [~skonto] [~susanxhuynh] any input on this problem? Have you came across such
> behavior?
> I'm ready to work on some patch, but currently I don't understand where to
> start, seems like driver is too fragile in this sense and something in
> mesos-spark integration is missing
