> {{InProcessAppHandle}} runs {{SparkSubmit}} in a dedicated thread, any exceptions thrown are logged and then the state is set to {{FAILED}}. It would be nice to expose the {{Throwable}} object  to the application rather than logging it and dropping it. Applications may want to manipulate the underlying {{Throwable}} / control its logging at a finer granularity. For example, the app might want to call {{Throwables.getRootCause(throwable).getMessage()}} and expose the message to the app users.
