                 Key: CASSANDRA-3621
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-3621
             Project: Cassandra
          Issue Type: Bug
    Affects Versions: 0.8.8
         Environment: java 1.6.26, linux
            Reporter: Zenek Kraweznik


My cassandra used to have adresses in 10.0.1.0/24 adresses, I moved it to 10.0.2.0/24 network (for security resons).

I want to test new cassandra before upgrading production instances. I've made snapshot and moved it to test servers (except system/LocationInfo* files).

Changes in configuration: ip adresses (seeds, listen address etc), cluster name. Test server are in 10.0.1.0/24 network.

In logs I see that test nodes are seeing each other, but when i try to show ring I get this error:
casstest1:/# nodetool -h 10.0.1.211 ring
