>  changed the behavior of driver process termination. Whereas before 
> `Process.destroyForcibly` was never called, now it is called (on Java VM's 
> supporting that API) if the driver process does not die within 10 seconds.
> This prevents apps which take longer than 10 seconds to shutdown gracefully 
> from shutting down gracefully. For example, streaming apps with a large batch 
> duration (say, 30 seconds+) can take minutes to shutdown.
