Сбои инициализации SolrCore

Я использую Solr-5.0.0, и когда я пытаюсь создать ядро, я получаю следующую ошибку в журнале.

SolrCore Initialization Failures
org.apache.solr.common.SolrException:org.apache.solr.common.SolrException: org.apache.solr.core.SolrCore.getRequestHandlers()Ljava/util/Map;

Это исключение в журнале

У меня была такая же проблема. Ваша основная конфигурация исходит из другой версии Solr.

Итак, несколько решений:

  • пересоздать файлы конфигурации с нуля
  • получить другую версию
  • попросите гуру Solr определить, в чем проблема :)

Это было из-за изменения версии для меня - person Juhan; 28.04.2015

Проверьте, нет ли у вас дубликатов .jars. Для меня это была дублированная банка в папке lib ядра. Он начал выдавать нулевые указатели после перехода на SOLR 5.

Я скопировал ядро ​​solr 5.0.0 на Windows 8.1 в установку solr 5.2.1 на Ubuntu 14.04. Во-первых, служба solr даже не запускалась. Затем я переместил ядро ​​в другое место и добавил его вручную (т.е. создал каталоги, попытался добавить ядро ​​из веб-приложения, скопировал недостающие файлы, попытался добавить ядро ​​из веб-приложения и т. д.). В какой-то момент я пришел к этому исключению.

Проблема заключалась в том, что у меня были solr-dataimporthandler-5.0.0.jar и solr-dataimporthandler-extras-5.0.0.jar в каталоге lib моего ядра. Поэтому я удалил их и скопировал solr-dataimporthandler-5.2.1 и solr-dataimporthandler-extras-5.2.1 из /opt/solr/dist в каталог lib моего ядра, и у меня больше не было исключений.
