я есть веб-сайт, работающий на инстансе Amazon EC2, и я пытаюсь заставить Solr взаимодействовать и работать с базой данных, которую я использую. Я могу использовать интерфейс администратора и проиндексировать примеры XML-файлов, но всякий раз, когда я пытаюсь импортировать одну из моих таблиц базы данных, я получаю сообщение об ошибке

SEVERE: Exception while processing: gamelydb document : SolrInputDocument[{}]:org.apache.solr.handler.dataimport.DataImportHandlerException:
 Unable to execute query: SELECT * FROM league Processing Document # 1

Вот мой файл data-config.xml. Я также добавил обработчик данных в файл solrconfig.xml.

<dataConfig>
  <dataSource type="JdbcDataSource"
              driver="com.mysql.jdbc.Driver"
              url="jdbc:mysql://www.mysite.com/mydb"
              user="root"
              password="mypassword"/>
  <document>
    <entity name="mydb"
            query="SELECT * FROM league">
       <field column="id" name="id" />
       <field column="leaguename" name="leaguename" />
    </entity>
  </document>
</dataConfig>

Есть идеи, почему это происходит? И просто дайте мне знать, если мне нужно что-то уточнить.

Поэтому я немного изменил URL и удалил http: //, и эта ошибка, похоже, исчезла. Однако ни одна из информации, кажется, не доступна для поиска через администратора. Теперь в каталоге данных есть несколько файлов (_1.fnm, _1.frq, ...). Вот что выводит solr в журнал.
