向Datastax添加插件

Question

我试图将胡萝卜聚类插件添加到Datastax( 4.7.3-1)中的Solr( 4.10.3)中。当我按照这些指令将JAR放在/usr/share/dse/solr/lib目录中时，我确实看到了java.​类.​路径中的库，但是它没有出现在plugins/​目录中。当我使用这个库时(虽然我看不见)，我得到了这个错误：

我错过了什么？

胡萝卜告诉你它需要阅读那些资源。你需要把它上传到DSE搜索，以便它可以被拾取。上传，为了您的方便而调整：

curl -s --data-binary @<xmlFileHere> -H 'Content-type:text/xml; charset=utf-8' http://<hostHere>:8983/solr/resource/<coreNameHere>/clustering/carrot2/default-attributes.xml

请确保将所需的所有资源上传到DSE搜索。DSE搜索不会从文件系统中读取它们，您必须将它们上传。
