title: Use Nutch with newest Elasticsearch
body: <p>Based on <a href="https://stackoverflow.com/questions/16729940/outofmemoryerror-for-bin-nutch-elasticindex-cluser-all-nutch-2-1">this question</a> I have managed to successfully integrate Nutch and Elasticsearch, albeit by downgrading my Elasticsearch version. How can I modify the Nutch source code to accommodate the latest version of Elasticsearch (0.90.2+)? I have tried modifying the Ivy dependency to this version of Elasticsearch and also modified Nutch's Elasticsearch compatibility code so it would build properly, but I end up with an error as Nutch times out waiting for a response from Elasticsearch; the two are unable to communicate.</p>
