I corrected the seed list and checked the cluster name. They are all good now. But still nodetool -ring shows only one node.
INFO 21:36:59,735 Starting Messaging Service on port 7000 INFO 21:36:59,748 Using saved token 113427455640312814857969558651062452224 Nodes a_ipadrr and b_ipaddr have the same token 113427455640312814857969558651062452224. a_ipadrr is the new owner. All the nodes seem to be using the same initial token, despite me specifying an initial_token in the config file. Is this an issue ? How do I force cassandra to use the token in the cassandra.yaml file ?
