Jongyoul Lee created SPARK-5197: ----------------------------------- Summary: Support external shuffle service in fine-grained mode on mesos cluster Key: SPARK-5197 URL: https://issues.apache.org/jira/browse/SPARK-5197 Project: Spark Issue Type: Improvement Components: Deploy, Mesos, Shuffle Reporter: Jongyoul Lee
I think dynamic allocation is almost satisfied on mesos' fine-grained mode, which already offers resources dynamically, and returns automatically when a task is finished. We, however, don't have a mechanism on support external shuffle service like yarn's way, which is AuxiliaryService. Because mesos doesn't support AusiliaryService, we think a different way to do this. - Launching a shuffle service like a spark job on same cluster -- Pros --- Support multi-tenant environment --- Almost same way like yarn -- Cons --- Control long running 'background' job - service - when mesos runs --- Satisfy all slave - or host - to have one shuffle service all the time - Launching jobs within shuffle service -- Pros --- Easy to implement --- Don't consider whether shuffle service exists or not. -- Cons --- exists multiple shuffle services under multi-tenant environment --- Control shuffle service port dynamically on multi-user environment In my opinion, the first one is better idea to support external shuffle service.
