我正在尝试在Datastax（v.4.7.3-1）中将Carrot Clustering plugin添加到Solr（v.4.10.3）。 当我按照these指令并将JAR放在/ usr / share / dse / solr / lib目录中时，我确实看到java.class。路径中的库但它没有出现在插件中/其他。 当我使用该库时（虽然我看不到它）我收到了这个错误：

Carrot告诉你需要阅读该资源。您需要将其上传到DSE搜索，以便可以选择它。上传根据您的方便调整：
curl -s --data-binary @<xmlFileHere> -H 'Content-type:text/xml; charset=utf-8' http://<hostHere>:8983/solr/resource/<coreNameHere>/clustering/carrot2/default-attributes.xml
确保上传到DSE搜索所需的所有资源。 DSE Search不会从文件系统中读取它们，而是必须上传它们。
