Nodetool does not show me all the nodes. Assuming I have three nodes A, B and C. The seedlist of A is localhost. Seedlist of B is localhost, A_ipaddr and seedlist of C is localhost,B_ipaddr,A_ipaddr. I have autobootstrap set to false for all 3 nodes since they all have the correct data and do not hav to migrate data from any particular node.
My problem here is why does n't nodetool ring show me all nodes in the ring ? I agree that the cluster thinks that only one node is present. How do I fix this ?
