  <p>I do not understand why spark is looking at the path there or how to change it. Any help would be appreciated. Thanks.</p>
  <p>Edit:
  This is what my core-site.xml file looks like.</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;
