[jira] [Commented] (CASSANDRA-5953) Replication validation is broken

["Sylvain Lebresne (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-5953?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13763057#comment-13763057 ] 

Sylvain Lebresne commented on CASSANDRA-5953:
---------------------------------------------

I don't know how much that matters, but as far as I can tell, we've never validated such a thing (I'm able to reproduce the exact same with the cli on 1.2 at least).

Which leads me to the question: do we really want to refuse it? Feels to me that handling non-existing nodes the same way than dead ones is rather sane. And actually I think that refusing this could be a tad painful if someone wants to up its RF.
