> Many external projects that are built on Spark support CLI scripts to launch their applications.  For example, the ADAM project has {{adam-submit}}, {{adam-shell}}, and {{adam-pyspark}} commands that mirror the Spark versions but modify the CLASSPATH and set some extra options to make it easy for the user.  However, because these applications can take a mix of Spark-specific and application-specific options, they need to use the internal CLI tools to separate them out before calling {{spark-submit}} or {{spark-shell}} (e.g., using {{gatherSparkSubmitOpts}}).  However, because this functionality is considered internal, it has changed a few times in the past.
> It would be great if there was a stable way that could be an "extensibility" API for people to make shell wrappers that would be unlikely to need significant changes when the Spark functionality changes.
