title: why password less ssh not working?
body: <p>I connected 3 data nodes(in all these data nodes pass-wordless is working fine) in my cluster which are working fine but when i try to connect another data node pass-wordless ssh not working in fourth data node.</p>
  
  <p>IP address of first three data nodes:</p>
  
  <pre><code>172.20.93.192(name node)
  172.20.94.189(data node)
  172.20.94.145(data node)
  172.20.94.193(data node)
  </code></pre>
  
  <p>now my fourth data node's IP address is 172.20.95.6 where password-less is not working.</p>
  
  <p>I am generating keys with</p>
  
  <pre><code>ssh-keygen -t rsa 
  </code></pre>
  
  <p>I am doing the same process for the fourth data node as above three data nodes but it is not working. Why? what may be the reason?</p>
