  <p>Where should i look for to correct the shuffle error. I have checked yarn-site.xml. I am running a cluster. I tried looking around but couldn't find any helpful stuff.</p>
  
  <p><strong>yarn-site.xml</strong></p>
  
  <pre><code>&lt;configuration&gt;
  
  &lt;!-- Site specific YARN configuration properties --&gt;
  
  &lt;property&gt;
   &lt;name&gt;yarn.nodemanager.aux-services &lt;/name&gt;
   &lt;value&gt;mapreduce.shuffle &lt;/value&gt;
  &lt;/property&gt;
  
  &lt;property&gt;
   &lt;name&gt;yarn.nodemanager.aux-services.mapreduce.shuffle.class &lt;/name&gt;
   &lt;value&gt;org.apache.hadoop.mapred.ShuffleHandler&lt;/value&gt;
  &lt;/property&gt;
  
  &lt;property&gt;
  &lt;name&gt;yarn.resourcemanager.resource-tracker.address&lt;/name&gt;
  &lt;value&gt;slave5:8031&lt;/value&gt;
  &lt;/property&gt;
  &lt;property&gt;
  &lt;name&gt;yarn.resourcemanager.scheduler.address&lt;/name&gt;
  &lt;value&gt;slave5:8030&lt;/value&gt;
  &lt;/property&gt;
  &lt;property&gt;
  &lt;name&gt;yarn.resourcemanager.address&lt;/name&gt;
  &lt;value&gt;slave5:8032&lt;/value&gt;
  &lt;/property&gt;
  
  
  
  &lt;/configuration&gt;
