[jira] [Commented] (SPARK-7367) spark-submit CLI --help -h
overrides the application arguments
[ https://issues.apache.org/jira/browse/SPARK-7367?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14528481#comment-14528481 ]
Sean Owen commented on SPARK-7367:
----------------------------------
Seems reasonable, but at the same time, why would this interact with your app's flags?

> 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
