title: Too many fetch failures on Hadoop
body: <p>I am a Hadoop/Pig beginner.</p>
  
  <p>I am trying to build a hadoop clsuter. With one data node and Master node also acting as data node.
  I have followed the instructions given in : <a href="http://www.michael-noll.com/tutorials/running-hadoop-on-ubuntu-linux-multi-node-cluster/" rel="nofollow">http://www.michael-noll.com/tutorials/running-hadoop-on-ubuntu-linux-multi-node-cluster/</a></p>
  
  <p>When I try to run the sample hadoop examples. I am getting "Too many fetch failures".</p>
  
  <p>I have all the names of the master and the host configured in /etc/hosts of both the master and the slave.
  I have also changed the somaxconn value to 1024.</p>
  
  <p>What am I missing here? Please help.</p>
