Subject Re: Remove node from cluster and have it run as a single node cluster by itself
Date Fri, 05 Oct 2012 11:47:49 GMT
I guess that the other nodes still gossips about the removed node. The 
node isn't removed from gossiper in the cluster until some amount of 
time have elapsed. My guess is that you haven't changed the cluster_name 
property  in the cassandra.yaml on the removed node.
