title: Hadoop on EC2 vs Elastic Map Reduce
body: <p>I'm trying to evaluate the differences between these two options. Here are some pros and cons I can think of :</p>
  
  <p>Elastic Map Reduce => Better support from Amazon, No need to administer cluster, More Expensive (?)
  EC2 + Hadoop => More control of your hadoop configuration, Cheaper (?)</p>
  
  <p>I'm wondering if anyone might have benchmarked the performance of EC2 + Hadoop vis a vis EMR? Is there any significant difference in cost for large cluster deployments? What other differences exist?</p>
