> 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.
> Is there any side-effect that this change will cause?
