Thanks All !! I think the intent of the JIRA https://issues.apache.org/ jira/browse/CASSANDRA-6961 was to primarily deal with stale information after outages and give opportunity for repairing the data before a node joins the cluster. If a node started with join_ring=false doesn't accept writes

Hi, I need to understand the use case of join_ring=false in case of node outages. As per https://issues.apache.org/jira/browse/CASSANDRA-6961, you would want join_ring=false when you have to repair a node before bringing a node back after some considerable outage. The problem I see with
