>             Project: Spark
>          Issue Type: Improvement
>          Components: Spark Core
>    Affects Versions: 2.3.0
>            Reporter: Marcelo Vanzin

>             Fix For: 2.4.0
> {{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.
