> The role launching code in the AM is based off Distributed Shell: uses a thread per launched container. This will have scale limits when launching a very large cluster if the assignments all come in near-simultaneously.
> Switching to a Java futures model would allow the AM to deploy via an executor that limited the number of operations active; possibly also support a better shutdown
