title: Zeppelin: How to restart sparkContext in zeppelin
body: <p>I am using Isolated mode of zeppelins spark interpreter, with this mode it will start a new job for each notebook in spark cluster. I want to kill the job via zeppelin when the notebook execution is completed. For this I did <code>sc.stop</code> this stopped the sparkContext and the job is also stopped from spark cluster. But next time when I try to run the notebook its not starting the <code>sparkContext</code> again. So how to do that?</p>
