Solr çekirdeği oluşturulamıyor

Question

Solr 5.2.1 örneğim var ve üretim adında yeni bir çekirdek oluşturmak istiyorum. Çözülmüş olan erişim haklarıyla ilgili birkaç sorunla karşılaştım, ancak aşağıdaki istisna benim için tamamen belirsiz. Yardım takdir edilir.

Answer 1

Size solrconfig.xml eski bir sürümünü kullanıyor görünüyor. Sınıf JsonUpdateRequestHandler en son Solr 4.x sürümlerinde kullanımdan kaldırıldı ve Solr 5.x'ten kaldırıldı. Bunun yerine UpdateRequestHandler kullanmalı ve Solr sürümüne göre solrconfig.xml'u güncellemeniz gerekir.
