> This is a regression caused by SOLR-5311
> There are two reasons why a core does not have a reference in clusterstate
> # It is starting up for the first time (core creation)
> # Somebody invoked a DELETEREPLICA when the node itself was down
> we neded to differentiate these two because for 1) the registration should succeed and
for #2 the registration should fail
> The only way to do that was to check for the presence of the attribute coreNodeName in
the core.properties. In case #1 it would be absent and in case#2 it would be present
> but when genericCoreNodeNames="${genericCoreNodeNames:false}"
> ZkController#getCoreNodeName(getCoreNodeName) behaves similarly for both the cases and
hence the failure
