title: Connect to Impala using impyla client with Kerberos auth
body: <p>I'm on a W8 machine, where I use Python (<strong>Anaconda</strong> distribution) to connect to <strong>Impala</strong> in our <strong>Hadoop</strong> cluster using the <strong>Impyla</strong> package. Our hadoop cluster is secured via <strong>Kerberos</strong>. I have followed the <a href="http://docs.ibis-project.org/configuration.html#working-with-secure-clusters-kerberos" rel="noreferrer">API REFERENCE</a> how to configure the connection. </p>
  
  <pre><code>    from impala.dbapi import connect
      conn = connect( host='localhost', port=21050, auth_mechanism='GSSAPI',
                 kerberos_service_name='impala')
  </code></pre>
  
  <p>We are using Kerberos GSSAPI with SASL</p>
  
  <pre><code>auth_mechanism='GSSAPI'
  </code></pre>
  
  <p>I have managed to install python-sasl library for WIN8 but still I encounter this error.</p>
  
  <pre><code>Could not start SASL: Error in sasl_client_start (-4) SASL(-4): no mechanism available: No worthy mechs found (code THRIFTTRANSPORT): TTransportException('Could not start SASL: Error in sasl_client_start (-4) SASL(-4): no mechanism available: No worthy mechs found',)
  </code></pre>
  
  <p>I wonder if I am still missing some dependencies.</p>
