Hi, In a cassandra cluster, when issueing ring command on every nodes, some can show all nodes in the cluster but some can only show some other nodes. All nodes share the same seed list. And even some of the nodes in the seed list have this problem. Restarting the problematic nodes won't solve it. Try closing firewalls with following commands
service iptables stop Still won't work. Anyone got a clue? Thanks very much. Yifeng
