we use SBT to create, test, run, and submit jobs. This tutorial will explain all the SBT commands you will use in our course. the Tools Installation page explains how to install SBT. We typically make the code and libraries into jar packages that are submitted to the spark cluster via Spark-submit. 1) Download and install:http://www.scala-sbt.org/2) Create the project:For example, now the project is called "Sparksample".
