Sorry I am only just looking at this now --
I am not so sure this is doing what you think. I think the notion of
"task" in MesosCoarseGrainedSchedulerBackend might be something different, its
really an "executor" in spark's terminology. Perhaps that code should have
some additional comments explaining that. Tasks are still handled in spark's
TaskScheduler / TaskSetManager etc.
@mgummelt can you confirm my understanding?
@timout please close this PR (unless I'm wrong about this code ...)
