Description

Mesos offers the capability of subscribing to multiple 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 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?
