С solr, настроенным для многоядерности (что может иметь значение, а может и не иметь), у меня была работающая тестовая система. solrconfig.xml жил в /solr-4.4.0/example/multicore/expertise/conf и по сути выглядел как пример файла solrconfig для многоядерности, за исключением следующих строк:
<dataDir>/data/website_data/solr_cores/expertise</dataDir>
<requestHandler name="/dataimport" class="org.apache.solr.handler.dataimport.DataImportHandler">
<lst name="defaults">
<str name="config">/data/website_data/solr_cores/expertise/data-config.xml</str>
</lst>
</requestHandler>
Поскольку мне нужен solr с поддержкой языка, я обновил solrconfig.xml некоторыми обработчиками выбора (ранее handleSelect был true) и новым updateRequestProcessorChain. Изменения в solrconf.xml выглядят следующим образом:
<lib dir="${user.dir}/../contrib/analysis-extras/lucene-libs/" /><!-- relative to solrs 'example' directory -->
<lib dir="${user.dir}/../contrib/analysis-extras/lib/" />
<lib dir="${user.dir}/../dist/" regex="solr-langid-.*\.jar" />
<lib dir="${user.dir}/../contrib/langid/lib/" />
<!-- required for language detection of input records -->
<updateRequestProcessorChain name="languages">
<processor class="solr.LangDetectLanguageIdentifierUpdateProcessorFactory">

Теперь я получаю сообщение об ошибке: Can't find resource '/data-config.xml' in classpath or 'multicore/expertise/conf/', cwd=/solr-4.4.0/example</str>
Путь данных не изменился. Файл data-config.xml существует там, где он должен быть, и его разрешения верны. Почему мой исходный solrconf.xml может найти data-config.xml, а мой новый — нет?
