[jira] [Created] (SPARK-22589) Subscribe to multiple roles in Mesos

Fabiano Francesconi created SPARK-22589:
-------------------------------------------

             Summary: Subscribe to multiple roles in Mesos
                 Key: SPARK-22589
                 URL: https://issues.apache.org/jira/browse/SPARK-22589
             Project: Spark
          Issue Type: Wish
          Components: Spark Core
    Affects Versions: 2.2.0, 2.1.2
            Reporter: Fabiano Francesconi


Mesos offers the capability of [subscribing to multiple roles|http://mesos.apache.org/documentation/latest/roles/]. I believe that Spark could easily be extended to opt-in for this specific capability.

From my understanding, this is the [Spark source code|https://github.com/apache/spark/blob/fc45c2c88a838b8f46659ebad2a8f3a9923bc95f/resource-managers/mesos/src/main/scala/org/apache/spark/scheduler/cluster/mesos/MesosSchedulerUtils.scala#L94] that regulates the subscription to the role. I wonder on whether just passing a comma-separated list of frameworks (hence, splitting on that string) would already be sufficient to leverage this capability.
