title: YARN does not show the finished job
body: <p>I installed Hadoop and YARN on my MAC. I am able to run the wordcount example and output results on HDFS (pesudo-distribute mode), I know <strong>my program is running data file on HDFS</strong> because I have to copy file to HDFS for it to run. However, when I check on my WEB UI for YARN, there is no record that any task has been accomplished. After research online, it seems that the application is still running locally. </p>
  
  <p>After start-yarn.sh, I can open Resource Manager web UI <code>http://localhost:8088/</code>, problem is that no task ever shows up. Furthermore, I cannot even access to my JobTracker Web UI. </p>
  
  <p>I found out the following link. it has a similar problem with mine, but the solution doesn't work for me </p>

  <p>My XML set-up is as follows</p>
  
  <p>mapred-site.xml</p>
  
  <pre><code>&lt;configuration&gt;
    &lt;property&gt;
        &lt;name&gt;mapred.job.tracker&lt;/name&gt;
        &lt;value&gt;localhost:9001&lt;/value&gt;
    &lt;/property&gt;
    &lt;property&gt;
      &lt;name&gt;mapred.framework.name&lt;/name&gt;
      &lt;value&gt;yarn&lt;/value&gt;
    &lt;/property&gt;
  &lt;/configuration&gt;
  </code></pre>
  
  <p>yarn-site.xml</p>
  
  <pre><code>&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;name&gt;yarn.nodemanager.aux-services.mapreduce.shuffle.class&lt;/name&gt;

  &lt;/property&gt;
  &lt;property&gt;
      &lt;name&gt;yarn.resourcemanager.address&lt;/name&gt;
      &lt;value&gt;localhost:9002&lt;/value&gt;
  &lt;/property&gt;
  </code></pre>
  
  <p>core-site.xml</p>
  
  <pre><code>&lt;configuration&gt;
      &lt;property&gt;
          &lt;name&gt;fs.defaultFS&lt;/name&gt;
          &lt;value&gt;hdfs://localhost:9000&lt;/value&gt;
      &lt;/property&gt;
  &lt;/configuration&gt;
  </code></pre>
  
  <p>Anyone knows what the problem is? Thanks</p>
