Marcelo Vanzin created SPARK-22941:
--------------------------------------
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.
