Hey i am trying to use icu analysis 2.7.0 with elasticsearch 1.7.1 every time i try to run analyze API on a field i get the following error "error":"NoClassDefFoundError[Could not initialize class org.apache.lucene.analysis.icu.segmentation.DefaultICUTokenizerConfig]","status":500} There is no log about this in the logs. My analyzer settings are "tokenized" : { "type" : "custom", "filter" : [ "word\_delimiter", "lowercase", "icu\_normalizer", "icu\_folding", "eng\_stm", "edge\_ngram" ], "tokenizer" : "icu\_tokenizer" }, I ll be able to provide any more information if needed. At the sametime icu\_collation works on the same index. ---

Can you describe all the steps? How do you install the plugin? Do you restart? All REST calls... Thanks! ---

Installation, We copy the jar related to the plugin into the plugins/analysis-icu directory. After this we bring up elasticsearch We dont use the /bin/plugin to install, as copying the jar worked for us, for previous versions of the same plugin and elasticsearch combination. ---

That can not work. You need to download the zip file and extract all its content. ``` bin/plugin ``` Does that. ---

Is this a new change with 1.7.1, because i have elasticsearch 1.5.4 running in our production system with analysis-icu 2.5, and it followed the same steps as above ---

Can you post the exact request you sent? Also could you try with elasticsearch 2.1.1? ---

Exact request for what ? I dont have the code pulled down for 2.1.1, its gonna take a while to get to 2.1.1. Right now we have to work with 1.7.1 ---

I'd like to see the request which corresponds to: > from kopf try to run a analyze And I'm not saying that you must upgrade. I'm just asking if you could try on a dev laptop the same with 2.1. It would help. ---
