body: <p>Hi i am installing hadoop in my machine,
  i created a new group and a user under the group</p>
  
  <pre><code>[hduser@localhost ~]$ ssh-keygen -t rsa -P "" Generating

  <p>I did generated private key , with empty password and moved to authorized_keys.
  next step is <code>cat $HOME/.ssh/id_rsa.pub &gt;&gt; $HOME/.ssh/authorized_keys</code>.</p>
  
  <p>But still while connecting to ssh localhost, my new user is asking me to enter password. which i didn't generate .</p>
