title: Hadoop single node installation error
body: <p>I am trying to install hadoop-1.1.2 on Mac Lion with java 6. </p>
  
  <p>I followed all the steps here <a href="http://hadoop.apache.org/docs/stable/single_node_setup.html" rel="nofollow">http://hadoop.apache.org/docs/stable/single_node_setup.html</a></p>
  
  <p>but when the i do <code>start-all.sh</code> only <code>namemode</code> and <code>jobtracker</code> starts but not <code>datanode</code>, <code>secondarynode</code> and <code>tasktracker</code>.</p>
  
  <p>here is the output:</p>
