title: How to reuse a cassandra node after decommission?
body: <p>I had a cluster with 2 nodes (node 1 and node 2).</p>
  
  <p>After decommissioning node 2 I wanted to use the server as a fresh Cassandra database for other purposes, but as soon as I restart this message appears:</p>
  
  <blockquote>
    <p>org.apache.cassandra.exceptions.ConfigurationException: This node was
    decommissioned and will not rejoin the ring unless
    cassandra.override_decommission=true has been set, or all existing
    data is removed and the node is bootstrapped again</p>
  </blockquote>
  
  <p>So I removed all existing data.</p>
  
  <p>But I don't want the node to be bootstrapped again (neither rejoin the previous ring) but to be a fresh new and pure Cassandra database to be used.</p>
  
  <p>The old node is not on the <em>seed</em> list.</p>
  
  <p>Cassandra version: 3.9</p>
  
  <p>EDIT: I think I was missunderstood, sorry for that. After the decommission I want to have:</p>
  
  <ul>
  <li>Db1: node 1</li>
  <li>Db2: node 2</li>
  </ul>
  
  <p>Two diferent databases with no correlation, totally separated. That's because we want to reuse the machine where node2 is hosted again to deploy a Cassandra DB in another enviroment.</p>
