             Summary: Allow SparkSubmit to throw exceptions instead of exiting / printing errors.
                 Key: SPARK-22941
                 URL: https://issues.apache.org/jira/browse/SPARK-22941
             Project: Spark
          Issue Type: Improvement
          Components: Spark Core
    Affects Versions: 2.3.0
            Reporter: Marcelo Vanzin


{{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.
