title: Hadoop Distributed cache object changed during job
body: <p>I have a number of sequenced Hadoop jobs in which I need a DistributedCache file.</p>
  
  <p>The driver class(Controller) receives the input from the previous job, modifies a file, it places it in the DistributedCache and it starts a new job. </p>
  
  <p>After the first job (i.e. in the second job), I get this error: </p>
  
  <pre><code>java.io.IOException: 
  The distributed cache object hdfs://xxxx/xx/x/modelfile2#modelfile2 
  changed during the job from 11/8/12 11:55 PM to 11/8/12 11:55 PM
  </code></pre>
  
  <p>Does anyone know what the problem might be ?</p>
