title: <job-tracker> and <name-node> in oozie pig configuraction action - where can i find them?
body: <p>I'm trying to run my first oozie workflow, simple <code>&lt;pig&gt;</code> action .<br>
  Can anyone help with these two tags:</p>
  <pre><code>    &lt;job-tracker&gt;[JOB-TRACKER]&lt;/job-tracker&gt;
      &lt;name-node&gt;[NAME-NODE]&lt;/name-node&gt;
  </code></pre>
  <p>As I understand, paramaters refer to existing configuration.<br>
  I'm using preconfigurered environment so can you please help where to find these values?</p>
