title: How to remove dead node out of the Cassandra cluster?
body: <ol>
  <li>I have the cassandra cluster of 12 nodes on EC2.</li>
  <li>Because of some failure we lost one of the node completely.I mean that machine do not exist anymore.</li>
  <li>So i have created the new EC2 instance with different ip and same token as that of the dead node and i also had the backup of data on that node so it works fine</li>
  <li>But the problem is the dead nodes ip still appears as a unreachable node in describe cluster.</li>
  <li>As that node (EC2 instance) does not exist anymore I can not use the <strong>nodetool decommission</strong> or <strong>nodetool disablegossip</strong> </li>
  </ol>
  
  <p><strong>How can i get rid of this unreachable node</strong> </p>
