[infinispan-issues] [JBoss JIRA] Commented: (ISPN-1348) Cluster ID generator initialization might not work when default cache is not clustered

    [ https://issues.jboss.org/browse/ISPN-1348?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12626020#comment-12626020 ] 

Galder Zamarreño commented on ISPN-1348:
----------------------------------------

Actually, this is not a bug at all, or at least in the way the current code is written. As per RpcManagerFactory, an RPCManager will be created per cache if the transport is not null, regardless of the cache's mode. So, even if the cache mode is LOCAL, if the cache manager has a transport set, getRpcManager won't return null and transport will be retrievable.

So, this is not a bug at all. It's true though that RpcManagerFactory should not create an RPCManager if the cache's mode is LOCAL, but that's a different issue which I'll create in a minute. And before changing that, I need ISPN-1366 fixed in the first place.

> This is related to the changes introduced as part of ISPN-1233. In Hot Rod servers, cluster ID generator initialization can fail to assign an initial view rank if the default cache is not clustered but other caches are. A better solution would be to simply cache the cache manager on construction, and if a new version for a clustered cache is created and the rank is not set yet (i.e. in cases such as AS7 where cache manager is started before the servers themselves), use the cached cache manager's transport to quickly calculate the view rank.
> This won't happen with Memcached because you can only interact with the default cache.
