I joined a ring, then left it
now my local ring is just showing my local cassndra node, like intended
but on the cassandra -f process, It keeps sending every 5 seconds
WARN 16:01:44,042 ClusterName mismatch from /220.127.116.11
big cluster!=Test Cluster
where big cluster is the cluster name used when in the previous ring
Why do I keep receiving this alerts? is it because 18.104.22.168 still tries to be in the ring?
Should I run nodetool decommission (token that had my node) on that node? to stop this alert?
thx for explanations
