title: Installing dependencies/libraries for EMR for spark-shell
body: <p>I am trying add extra libraries to scala used through spark-shell through the Elsatic MapReduce inatance. But I am unsure how to go by this, is there a build tool that is used when spark-shell runs? </p>
  
  <p>All i need to do is install a scala library and have it run through the spark-shell version of scala, Im not sure how to go about this since Im not sure how the EMR instance installs scala and spark.</p>
