title: How is the Spark master elected in a Datastax Enterprise cluster?
body: <p>How is the Spark master elected in a Datastax Enterprise cluster? I have looked at the configurations in <code>/etc/dse/dse-env.sh</code> and <code>/etc/dse/spark/spark-defaults.conf</code> and <code>/etc/dse/spark/spark-env.sh</code>. But I cannot find it any of those locations?</p>
  
  <p>On our cluster the Spark master keeps on moving from one node to another after the restart of the services?</p>
