Here's how we go about adding the sbteclipse plugin:

1. Add this to the global plugin file:

        $ mkdir /home/hduser/.sbt/0.13/plugins
        $ echo addSbtPlugin("com.typesafe.sbteclipse" % "sbteclipse-plugin" % "5.1.0" )  > /home/hduser/.sbt/0.13/plugins/plugin.sbt

2. Alternatively, you can add the following to your project:

        $ cd <project-home>
        $ echo addSbtPlugin("com.typesafe.sbteclipse" % "sbteclipse-plugin" % "5.1.0" )  > plugin.sbt

3. Start the SBT shell without any arguments:

        $ sbt

4. Type eclipse command and it will make an Eclipse-ready project:

        $ eclipse

5. Navigate to File | Import | Import existing project into the workspace to load the project into Eclipse:

 

Now you can develop the Spark application in Scala using Eclipse and SBT.
