title: Why still getting JNA error on Cassandra startup, even the jna.jar and platform.jar are there in the lib dir?
body: <p>I have downloaded and copied Jna.jar and Platform.jar to /usr/cassandra/apache-cassandra-1.0.7/lib folder, but still see the following error on Cassandra startup, am I missing anything? </p>
  
  <pre><code>"On cassandra JNA not found. Native methods will be disabled."
  </code></pre>
