title: Eclipse and Hadoop 2.2 Location Status Updater Error
body: <p>I'm using Linux Mint 16 and have installed Eclipse (Kepler) and Hadoop 2.2.0. I have set Eclipse to use the Map/Reduce perspective and I have created a new Hadoop location. When I created the location, I went into the Advanced tab and set the path for:</p>
  
  <ul>
  <li>dfs.datanode.data.dir</li>
  <li>dfs.namenode.name.dir</li>
  <li>dfs.data.dir</li>
  <li>dfs.name.dir</li>
  </ul>
  
  <p>When I click the + sign next to the location name, I get the following error:</p>
  
  <blockquote>
    <p>'Map/Reduce location status updater' has encountered a problem. An internal error occurred during "Map/Reduce location status updater".</p>
  </blockquote>
  
  <p>When I click on Details, I get the following:</p>
  
  <blockquote>
    <p>An internal error occurred during "Map/Reduce location status updater". java.land.NullPointerException</p>
  </blockquote>
  
  <p>I have seen a few items on stackoverflow regarding Hadoop versions prior to 2.2 and they haven't solved this error for me. Any suggestions?</p>
