By "scale the cluster up and down" do you mean:

1) adding/removing spark executors based on the load? How is that from the
dynamic resource allocation that is already supported by spark?

2) Or do you mean scaling the number of servers in a cluster (e.g. like AWS
autoscaling)? If so I'm afraid it's out of the scope of spark itself.
