Joseph Naegele commented on NUTCH-2234:
---------------------------------------

Understood. The update to Lucene analyzers requires minor programmatic API 
changes in scoring-similarity, but nothing big. None of the indexers have 
tests, so I'm testing indexer-elastic manually for now. Unfortunately updating 
Elasticsearch breaks the plugin due to differences in guava versions: 
indexer-elastic depends on guava-18.0, which it declares in its plugin.xml, but 
guava-16.0.1 is a Nutch-wide dependency (for Hadoop). We avoided this issue in 
the past by also updating Nutch's Hadoop dependency from 2.4.0 -> 2.7.1, which 
is why Tien created NUTCH-2246. I'll open the PR with all aforementioned 
dependency updates.

> Upgrade to elasticsearch 2.1.1
