[infinispan-issues] [JBoss JIRA] Commented: (ISPN-1270) Hash cache configurations to make sure they're symmetric in cluster

[Mircea Markus (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-1270?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12617506#comment-12617506 ] 

Mircea Markus commented on ISPN-1270:
-------------------------------------

I think the idea with a hash is nice, as it is quick and I'd expect most of the users to configure cluster correctly, so no point sending the entire config around at boot time. But if there are differences, it might make sense to do some more work and point out exactly what the problem is( especially if the custom config is large).

> On startup, verify that all nodes in the cluster have identical cache configuration, to avoid issues like the one presented in the user forum post.
> A hash (that's plattform/jvm independent) could be calculated on startup and coordinator could verify that all cache configurations have the same hash all across the cluster.
