title: Cassandra cqlsh "unable to connect to any servers"
body: <p>I get the following message when executing cqlsh.bat on the command line</p>
  
  <pre><code>Connection error: ('Unable to connect to any servers', {'127.0.0.1': ProtocolError("cql_version '3.3.0' is not supported by remote (w/ native protocol). Supported versions: [u'3.2.0']",)})
  </code></pre>
  
  <p>I'm running Python version 2.7.10 along with Cassandra version 2.2.1. Not sure if it's related but when I start the Cassandra server I need to run "Set-ExecutionPolicy Unrestricted" on PowerShell or else it doesn't work.</p>
