Subject: [PATCH] [BUILD] Add the ability to launch spark-shell from SBT.
Now you can quickly launch the spark-shell without building an assembly. For quick development iteration run `build/sbt ~sparkShell` and calling exit will relaunch with any changes.
Author: Michael Armbrust <michael@databricks.com>
Closes #4438 from marmbrus/sparkShellSbt and squashes the following commits:
