Hi, I use elasticSearch 2.2 through Java Api. I need use icu\_collation filter from Analysis ICU plugin. I included Analysis ICU plugin library, but still get error: java.lang.IllegalArgumentException: Unknown TokenFilter type [icu\_collation] for [myCollator]. I use node client through Java. Do I need to allow this plugin somewhere? Can you guys help me? Thanks ---

I solved this problem. I used this implementation of client node (first post from dbaggott): [Support for loading a plugin in a client node is missing](https://github.com/elastic/elasticsearch/issues/15927) ---
