Subject Re: Remove node from cluster and have it run as a single node cluster by itself
Date Fri, 05 Oct 2012 15:53:53 GMT
i believe the system keyspace keeps track of the cluster topology.
even though you changed info in yaml, the system keyspace still knows
about the other nodes.  remove the system keyspace files from data dir
and try again
