title: What does the nodetool status note about replication settings actually mean?
body: <p>Recently I've seen the following message displayed by nodetool status:</p>
  
  <pre><code>Note: Non-system keyspaces don't have the same replication settings, effective ownership information is meaningless
  </code></pre>
  
  <p>I was wondering what it means and whether it indicates any kind of problem. </p>
  
  <p>Thanks for your attention</p>
