Mark Miller updated SOLR-10316:
-------------------------------
Description:
We only use core node name and collection to match in ZK#unregister(core).
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.
was:
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.
> Unloading a core can remove a ZK SolrCore registration entry for the wrong
> SolrCore.
