title: Cassandra-3.10 on Ubuntu 14.04 malfunctions on machine restart
body: <p>Here's what I have:<br>
  - I installed a cassandra 3.10 version on my Ubuntu 14.04.<br>
  - I have it running as a service.<br>
  - I've modified cassandra.yaml file to listen to my <strong>node</strong><br>
  - I have a single node.  </p>
  
  <p>Everything was working fine; until I had to restart my machine. I hit the command:<code>sudo service cassandra stop</code> (I tried restarting my machine without stopping cassandra as well), then restarted my machine. When i got back, and tried to access through cqlsh, I get the following error:</p>
  
  <pre><code>Connection error: ('Unable to connect to any servers', {'192.168.2.202': error(111, "Tried connecting to [('192.168.2.202', 9042)]. Last error: Connection refused")})
  </code></pre>
  
  <p>When I look for <code>nodetool status</code>, instead of a valid Host ID, I see <code>null</code>. I tried <code>nodetool refresh</code>, but no luck.</p>
  
  <p>Can anyone tell me what's wrong?</p>
