---------------------------------------
I think this bug has been fixed since 1.4
help in app args:
{noformat}
$ spark-submit --master local --class MyClass /my.jar --help
Exception in thread "main" scala.MatchError: List(--help) (of class
scala.collection.immutable.$colon$colon)
{noformat}
help in spark args:
{noformat}
$ spark-submit --master local --class MyClass --help /my.jar
Usage: spark-submit [options] <app jar | python file> [app arguments]
...
{noformat}
> spark-submit CLI --help -h overrides the application arguments

> Key: SPARK-7367
> URL: https://issues.apache.org/jira/browse/SPARK-7367
> Project: Spark
> Issue Type: Bug
> Components: Spark Submit
> Reporter: Gianmario Spacagna
> Priority: Minor
>
> The spark-submit script will parse the --help argument even if is provided as
> application argument.
> E.g.
> spark-submit --master local[*] --driver-memory 4G --class bar.foo.MyClass
> /MyLocalJAR.jar --help
> or
> spark-submit --master local[*] --driver-memory 4G --class bar.foo.MyClass
> /MyLocalJAR.jar -h
> If my application is using a parsing library, such as Scallop, then it will
> never be able to run the application with --help as argument.
> I think the spark-submit script should only print the help message when is
> provided as single argument like this:
> spark-submit --help
> or it should provide a separator for trailing arguments:
> spark-submit --master local[*] --driver-memory 4G --class bar.foo.MyClass
> /MyLocalJAR.jar -- --help --arg1 --arg2
