SolrCloud OpenNLP error Can't find resource 'opennlp/en-sent.bin' in classpath or '/configs/_default'

Question

I have error when using Apache OpenNLP with Solr (ver. 7.3.0) in Cloud mode. When I add field type to managed-schema using open nlp like this:

<fieldType name="text_opennlp" class="solr.TextField">
      <analyzer>
        <tokenizer class="solr.OpenNLPTokenizerFactory"
          sentenceModel="opennlp/en-sent.bin"
          tokenizerModel="opennlp/en-token.bin"
        />
      </analyzer>
    </fieldType>

    <field name="content" type="text_opennlp" indexed="true" termOffsets="true" stored="true" termPayloads="true" termPositions="true" docValues="false" termVectors="true" multiValued="true" required="true"/>

and I have following error:

test_collection_shard1_replica_n1: org.apache.solr.common.SolrException:org.apache.solr.common.SolrException: Could not load conf for core test_collection_shard1_replica_n1: Can't load schema managed-schema: org.apache.solr.core.SolrResourceNotFoundException: Can't find resource 'opennlp/en-sent.bin' in classpath or '/configs/_default', cwd=D:\utils\solr-7.3.0-7\solr-7.3.0-7\server Please check your logs for more information

I have downloaded solr var 7.3.0-7 from https://builds.apache.org/job/Solr-Artifacts-7.3/lastSuccessfulBuild/artifact/solr/package/

I tried to put model files to: D:\utils\solr-7.3.0-7\solr-7.3.0-7\server but it didn't help.

Maybe I need to put model files somewhere else?

Maybe someone used apache open nlp with solr and knows where this models should be located? — Alexey Ponomarenko
Maybe I need to use Zookeeper to upload files somehow but how can I do this properly? — Alexey Ponomarenko

You need to put those files ("en-sent.bin" and the other one) into core's conf directory.

That is D:\utils\solr-7.3.0-7\solr-7.3.0-7\server\{core_name}\conf.

Then use the files directly. Following should be the xml configuration.

<tokenizer class="solr.OpenNLPTokenizerFactory"
          sentenceModel="en-sent.bin"
          tokenizerModel="en-token.bin"
        />
