Marcelo Vanzin updated SPARK-4924:
----------------------------------
Attachment: spark-launcher.txt
Attaching a mini-spec to describe the motivation and a proposal for the
library. I'm currently working on a prototype based on that spec and should
have something to share soon-ish.
> Factor out code to launch Spark applications into a separate library
> --------------------------------------------------------------------

>
> One of the questions we run into rather commonly is "how to start a Spark
> application from my Java/Scala program?". There currently isn't a good answer
> to that:
> - Instantiating SparkContext has limitations (e.g., you can only have one
> active context at the moment, plus you lose the ability to submit apps in
> cluster mode)
> - Calling SparkSubmit directly is doable but you lose a lot of the logic
> handled by the shell scripts
> - Calling the shell script directly is doable, but sort of ugly from an API
> point of view.
> I think it would be nice to have a small library that handles that for users.
> On top of that, this library could be used by Spark itself to replace a lot
> of the code in the current shell scripts, which have a lot of duplication.
