title: Hadoop 2.2.0 Eclipse Plugin
body: <p>I have installed hadoop-2.2.0 (single node cluser) and maven3.3.1 on my pc. I want to program MapReduce code in eclipse. So my questions are:</p>
  
  <ol>
  <li>What is the relationship between mapreduce and maven?</li>
  <li>How do I debug the code in eclipse? A tutorial says that I should first install a hadoop eclipse plugin in an old version, but it seems there isn't a plugin for the new version hadoop-2.2.0. How can I solve this?</li>
  </ol>
