title: Slave's datanodes not starting in hadoop
body: <p>I followed <a href="http://javadev.org/docs/hadoop/centos/6/installation/multi-node-installation-on-centos-6-non-sucure-mode/" rel="nofollow">this</a> tutorial and tried to setup a multinode hadoop cluster on centOS. After doing all the configurations and running <code>start-dfs.sh</code> and <code>start-yarn.sh</code>, this is what <code>jps</code> outputs:</p>
  
  <pre><code>Master
  26121 ResourceManager
  25964 SecondaryNameNode
  25759 NameNode
  25738 Jps
  
  Slave 1
  19082 Jps
  17826 NodeManager
  
  Slave 2
  17857 Jps
  16650 NodeManager
  </code></pre>
  
  <p>Data node is not started on slaves.</p>
  
  <p>Can anyone suggest what is wrong with this setup?</p>
