title: Cannot start cassandra in DataStax Enterprise (single node scenario)
body: <p>I'm trying to setup cassandra on single node using DataStax Enterprise (this is only for experimental usage of DataStax Enterprise on non-production server). 
  I'm using amazon image which is rhel based and I've used following instructions to install DataStax Enterprise: <a href="http://docs.datastax.com/en/datastax_enterprise/4.7/datastax_enterprise/install/installRHELdse.html" rel="nofollow">http://docs.datastax.com/en/datastax_enterprise/4.7/datastax_enterprise/install/installRHELdse.html</a></p>
  
  <p>Installation passes successfully and then I try to start DSE with following instructions: <a href="http://docs.datastax.com/en/datastax_enterprise/4.7/datastax_enterprise/startStop/refDseServ.html" rel="nofollow">http://docs.datastax.com/en/datastax_enterprise/4.7/datastax_enterprise/startStop/refDseServ.html</a> (I only need cassandra, therefore I use default option where other services are disabled)
  <code>HADOOP_ENABLED=0 SOLR_ENABLED=0 SPARK_ENABLED=0</code></p>
  
  <p>Starting dse:</p>
  
  <pre><code>sudo service dse start
  Starting DSE daemon : dse
  DSE daemon starting with just Cassandra enabled (edit /etc/default/dse to enable)
  </code></pre>
  
  <p>Checking netstats output:</p>
  
  <pre><code>netstat -nltp
  (No info could be read for "-p": geteuid()=500 but you should be root.)
