The zkcli command "linkconfig" should take care of that. You'd need to reload the collection after making the change. If you're using a version prior to 4.4, reloading doesn't work, you need to restart Solr completely. You can see what config a collection is using with the Cloud->Tree section of the admin UI. Open /collections and click on the collection. At the bottom of the right-hand window, it has a small JSON string with "configName" in it. I don't know of a way to easily get this information from Solr with a program. If your program is Java, you could very likely grab the zookeeper object from CloudSolrServer and find it that way, but I have no idea how to write that code. Thanks, Shawn
