title: Is there a simple Python map-reduce framework that uses the regular filesystem?
body: <p>I have a few problems which may apply well to the Map-Reduce model. I'd like to experiment with implementing them, but at this stage I don't want to go to the trouble of installing a heavyweight system like Hadoop or Disco.</p>
  
  <p>Is there a lightweight Python framework for map-reduce which uses the regular filesystem for input, temporary files, and output?</p>
