Thanks Ongen. Unfortunately I'm not able to follow your instructions either. In particular:
> > sbt compile > sbt run <arguments if any> This doesn't work for me because there's no program on my path called "sbt". The instructions in the Quick Start guide are specific that I should call "$SPARK_HOME/sbt/sbt". I don't have any other executable on my system called "sbt". Did you download and install sbt separately? In following the Quick Start guide, that was not stated as a requirement, and I'm trying to run through the guide word for word.
