title: Retry processing of failed files in Hadoop
body: <p>I've a Hadoop Map-Reduce program which is nothing but a simple file processing code. Each mapper is having one file as the input.</p>
  
  <p>My Reducer part is empty. All the work is done in map() method.</p>
  
  <p>Now the problem that I'm facing now is -</p>
  
  <p>If the file processing operation failes inside mapper, I'm not able to tell my Hadoop job to wait for some constant seconds before retrying from the same failed file and moving ahead.</p>
  
  <p>Is there any way/configuration to specify as such ?</p>
  
  <p>Let me know if anyone has encountered such use-case.</p>
