title: how to execute hadoop jar from HDFS FileSystem?
body: <p>I'm always executing job from local File system as following</p>
  
  <pre><code>hadoop jar /home/usr/jar/myjar.jar com.test.TestMain 
  </code></pre>
  
  <p>How can I execute same command but myjar.jar will be in hdfs ?</p>
  
  <p>Something like   </p>
  
  <pre><code>hadoop jar hdfs:///home/usr/jar/myjar.jar com.test.TestMain 
  </code></pre>
  
  <p>But of course this doesn't work...</p>
