             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. Please leave comments.
