title: Error: unable to connect to cassandra server. Unconfigured table
body: <p>I am trying to connect to cassandra, which is running on local desktop, via cassandra-driver for python using this simple code. </p>
  
  <pre><code> from cassandra.cluster import Cluster
   cluster = Cluster()
   session = cluster.connect()
  </code></pre>
  
  <p>and getting this error: <strong><em>NoHostAvailable: ('Unable to connect to any servers', {'127.0.0.1': InvalidRequest(u'code=2200 [Invalid query] message="unconfigured table schema_keyspaces"',)})</em></strong></p>
  
  <p>From the logs of cassandra, I see how it does establish connection, but it gets this errors:</p>
  
  <pre><code>DEBUG 05:51:00 Responding: ERROR INVALID: unconfigured table schema_columnfamilies, v=4
  DEBUG 05:51:00 Responding: ERROR INVALID: unconfigured table schema_usertypes, v=4
  DEBUG 05:51:00 Responding: ERROR INVALID: unconfigured table schema_columns, v=4
  DEBUG 05:51:00 Responding: ERROR INVALID: unconfigured table schema_functions, v=4
  DEBUG 05:51:00 Responding: ERROR INVALID: unconfigured table schema_aggregates, v=4
  DEBUG 05:51:00 Responding: ERROR INVALID: unconfigured table schema_triggers, v=4
  </code></pre>
  
  <p>Any help to solve this problem with unconfigured tables will be appreciated.</p>
