title: Datastax driver Issue getting TransportException
body: <p>I'm using datastax driver version</p>
  
  <pre><code>&lt;datastax.version&gt;2.0.8&lt;/datastax.version&gt;
  </code></pre>
  
  <p>and soon after my app initializes, I see TransportException error from datastax.
  I've looked up online and found and a jira ticket opened on a similar issue from datastax but that doesn't provide enough information about the resolution.</p>
