title: Nutch in Hadoop 2.x
body: <p>I have a three-node cluster running Hadoop 2.2.0 and HBase 0.98.1 and I need to use a Nutch 2.2.1 crawler on top of that. But it only supports Hadoop versions from 1.x branch. By now I am able to submit a Nutch job to my cluster, but it fails with java.lang.NumberFormatException.
  So my question is pretty simple: how do I make Nutch work in my environment?</p>
