我正在尝试整合cassandra和solr。我使用的是solr -6.6.0版本，cassandra 3.10版本和java 8。
添加所有必要的配置文件后，我无法进行集成。我错过了任何罐子或冲突的罐子吗？我也尝试使用solr 7.1.0并遇到同样的问题。任何指针都会有所帮助。
添加到solarconfig.xml

请帮忙！
答案 0 :(得分：2)
您正尝试使用CQL端口9042上的JDBC协议连接到Cassandra。您需要通过调用nodetool enablethrift启用Thrift支持，然后您应该能够使用端口9160（或任何您拥有的端口）进行连接在你的Cassandra配置中）
