title: Cloudera Manager inspector not running on hosts
body: <p>I currently have 3 machines, all bootcamped macs running Ubuntu, and am trying to set them up as a Hadoop cluster using CDH 5. While using the installer wizard, when it 'inspects the hosts for correctness I get the errors shown below.</p>
  
  <p><a href="https://i.stack.imgur.com/8ZF6o.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/8ZF6o.png" alt="enter image description here"></a></p>
  
  <p>The inspector fails on all hosts and it says</p>
  
  <pre><code>IOException thrown while collecting data from host: Connection refused
  </code></pre>
  
  <p>While setting up the machines the only thing I did before running the cloudera manager installer was enable ssh.</p>
  
  <p>In the hosts file all have localhost and my user on 127.0.0.1</p>
  
  <p>Any ideas on why the connection was refused orhat I could do to fix it?</p>
