title: Changing Cluster Name in Cassandra
body: <p>I have a cluster with 2 machines (centos7 and cassandra 3.4), 192.168.0.175 and 192.168.0.174. The seed is the 192.168.0.175.</p>
  
  <p>I simply want to change the cluster name. Peace of cake should be.</p>
  
  <p>I did on each cluster : </p>
  
  <ul>
  <li><p><code>update system.local set cluster_name = 'America2' where key='local';</code></p></li>
  <li><p>i did the nodetool flush</p></li>
  <li><p>i updated the cassandra.yaml with the new name</p></li>
  <li><p>restarted cassandra.</p></li>
  </ul>
  
  <p>When i cqlsh any if describes me as connected to new cluster_name America2</p>
  
  <p>When i run nodetool describecluster it shows the old cluster name America</p>
  
  <p>If i stop cassandra on both machines and i try to restart them i find in logs the good old error : </p>
  
  <p><code>org.apache.cassandra.exceptions.ConfigurationException: Saved cluster name America != configured name America2</code></p>
  
  <p>So....what am i doing wrong!?</p>
