    How about removing this method and redirecting the calls? Was there a 
dependency management reason you didn't want to do that?

>
> For scenarios where the AppMaster is launched from a docker image, it would 
> be ideal to use the installed Flink rather than rely on a special file layout 
> in the sandbox directory.
> This is related to DCOS integration, which (in 1.2) will launch the AppMaster 
> via Marathon (as a top-level DCOS service).  The existing code assumed that 
> only the dispatcher (coming in 1.3) would launch the AppMaster.
