I’m pretty sure you could change the name when you ADDREPLICA using a core.name property. I don’t know if you can when you initially create the collection though.
The CLUSTERSTATUS command will tell you the core names: https://cwiki.apache.org/confluence/display/solr/Collections+API#CollectionsAPI-api18 That said, this tool might make things easier. https://github.com/whitepages/solrcloud_manager # shows cluster status, including core names: java -jar solrcloud_manager-assembly-1.4.0.jar -z zk0.example.com:2181/myapp # deletes a replica by node/collection/shard (figures out the core name under the hood) java -jar solrcloud_manager-assembly-1.4.0.jar deletereplica -z zk0.example.com:2181/myapp -c collection1 --node node1.example.com --slice shard2 I mention this tool every now and then on this list because I like it, but I’m the author, so take that with a pretty big grain of salt. Feedback is very welcome.
