> CMS: restarting a CMS node with different ip address
> ----------------------------------------------------

> Key: CASSANDRA-19219
> URL: https://issues.apache.org/jira/browse/CASSANDRA-19219
> Project: Cassandra
> Issue Type: Bug
> Components: Transactional Cluster Metadata
> Reporter: Paul Chandler
> Assignee: Alex Petrov

> I am simulating running a cluster in Kubernetes and testing what happens when
> a pod goes down and is re created with a new ip address, the data is all
> stored on a detached volume so when the new pod is created all the old data
> for the node is reattached. In 4.0 this is handled correctly the node will
> come back up with the same hostid, tokens etc, just a new ip address and the
> cluster is healthy throughout.
>
> To simulate this I create a 3 node cluster on a local machine using 3
> loopback addresses
> 127.0.0.1
> 127.0.0.2
> 127.0.0.3
> I then run nodetool -p 7199 reconfigurecms datacenter1:3 --sync to create 3
> CMS nodes
> I then bring down 127.0.0.1 and replace the rpc_address and listen_address
> with 127.0.0.4 and re start the node. The node then hangs with this as the
> last error message:
> (8821185654333640868,9200867415893016118]=ForRange\{lastModified=Epoch{epoch=12},
