Gianmario Spacagna updated SPARK-7367:
--------------------------------------
Description:
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
