Kann nicht Solr Core

Question

Ich habe eine Solr 5.2.1 Instanz und ich möchte eine neue Kern namens Produktion erstellen. Ich hatte mehrere Probleme mit Zugriffsrechten, die gelöst wurden, aber die folgende Ausnahme ist mir völlig unklar. Hilfe wird geschätzt.

Answer 1

Es scheint, dass Sie eine alte Version von solrconfig.xml verwenden. Die Klasse JsonUpdateRequestHandler wurde in den neuesten Versionen von Solr 4.x eingestellt und aus Solr 5.x entfernt. Sie sollten stattdessen UpdateRequestHandler verwenden und Ihre solrconfig.xml entsprechend Ihrer Solr-Version aktualisieren.
