    Hey @sryza - I did a straw poll offline discussing this with a few other contributors. The consensus was that it might be better to have a `--conf` flag with an `=` sign instead of representing spark conf properties directly as flags.
    
    I.e. `--conf spark.app.name=blah`
    
    On admittedly bad thing about this approach is that if users have arguments with spaces in them, they will have to quote the entire thing:
    
    ```
    ./bin/spark-submit --conf "spark.app.name=My app"
    ```
    
    Which might not be intuitive, so it would be good to document that (provided you are generally okay with this proposed syntax).
