Side note: When running SolrCloud, you should not use a significantly different SolrJ version. Significantly different versions may not communicate correctly -- especially when the *major* version is different. SolrJ is generating the error you see, because you're using CloudSolrClient and that client requires a collection, unless the handler that you are accessing is one that works on the whole cluster, such as /admin/collections. Because the /admin/info/system request is node-specific, it doesn't make sense to try to use it with CloudSolrClient -- you won't know which node it's being sent to. Use HttpSolrClient instead. See this comment I wrote on an issue in Jira, with a code example: https://issues.apache.org/jira/browse/SOLR-8216?focusedCommentId=14976963&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14976963 Thanks, Shawn
