[jira] [Created] (SOLR-10316) Unloading a core can remove a ZK SolrCore registration entry for the wrong SolrCore.

Mark Miller created SOLR-10316:
----------------------------------

             Summary: Unloading a core can remove a ZK SolrCore registration entry for the wrong SolrCore.
                 Key: SOLR-10316
                 URL: https://issues.apache.org/jira/browse/SOLR-10316
             Project: Solr
          Issue Type: Bug
      Security Level: Public (Default Security Level. Issues are Public)
            Reporter: Mark Miller
            Assignee: Mark Miller


While we pass core node name to the Overseer for ZK unregistration during unload, we don't consult it and just use core node name and collection.

This means if a registration was taken over (either via manual user interaction or auto add replicas), unloading a core can remove a ZK entry it should not.
