solr - sunspot: Error when reindexing (Errno::ECONNREFUSED: Connection refused)

Question

World. I'm new in rais. I have the problem:

After I use class for steamming

 <filter class="solr.HunspellStemFilterFactory" dictionary="ru_RU.dic" affix="ru_RU.aff" ignoreCase="true" />

in "schema.xml"

<fieldType name="text" class="solr.TextField" indexed="true" stored="true" multiValued="true" positionIncrementGap="100">
   <analyzer type="index">
      <tokenizer class="solr.LowerCaseFilterFactory"/>
    <filter class="solr.HunspellStemFilterFactory" dictionary="ru_RU.dic" affix="ru_RU.aff" ignoreCase="true" />
    <filter class="solr.EdgeNGramFilterFactory" minGramSize="2" maxGramSize="25" side="front" />
    <filter class="solr.EdgeNGramFilterFactory" minGramSize="2" maxGramSize="25" side="back" />
   </analyzer>
   <analyzer type="query">
       <tokenizer class="solr.LowerCaseFilterFactory"/>
    <filter class="solr.HunspellStemFilterFactory" dictionary="ru_RU.dic" affix="ru_RU.aff" ignoreCase="true" /> 
   </analyzer>
</fieldType>

I restart solr-server and then can't reindexing (rake sunspot:reindex). Get this error:

Errno::ECONNREFUSED: Connection refused - {:data=>"<?xml version=\"1.0\" encoding=\"UTF-8\"?><delete><query>type:Ad</query></delete>", :headers=>{"Content-Type"=>"text/xml"}, :method=>:post, :params=>{:wt=>:ruby}, :query=>"wt=ruby", :path=>"update", :uri=>#<URI::HTTP:0xa2a3280 URL:http://localhost:8982/solr/development/update?wt=ruby>, :open_timeout=>nil, :read_timeout=>nil, :retry_503=>nil, :retry_after_limit=>nil}

If I delete hunspell from schema.xml reindexing are completed. ru_RU.dic and ru_RU.aff in utf-8.

Thank you in advance)
