> {{SparkSubmit}} now can be called by the {{SparkLauncher}} library (see SPARK-11035). But if the caller provides incorrect or inconsistent parameters to the app, {{SparkSubmit}} will print errors to the output and call {{System.exit}}, which is not very user friendly in this code path.
> We should modify {{SparkSubmit}} to be more friendly when called this way, while still maintaining the old behavior when called from the command line.
