[jira] [Updated] (CASSANDRA-19221) CMS: Nodes can restart with new ipaddress already defined in the cluster

Alex Petrov updated CASSANDRA-19221:
Description:
I am simulating running a cluster in Kubernetes and testing what happens when
several pods go down and ip addresses are swapped between nodes. In 4.0 this
is blocked and the node cannot be restarted.
To simulate this I create a 3 node cluster on a local machine using 3 loopback
addresses
{code}
127.0.0.1
127.0.0.2
127.0.0.3
{code}
The nodes are created correctly and the first node is assigned as a CMS node as
shown:
{code}
bin/nodetool -p 7199 describecms
{code}
Cluster Metadata Service:
{code}
Members: /127.0.0.1:7000
Is Member: true
Service State: LOCAL
{code}
At this point I bring down the nodes 127.0.0.2 and 127.0.0.3 and swap the ip
addresses for the rpc_address and listen_address
The nodes come back as normal, but the nodeid has now been swapped against the
ip address:

On previous tests of this I have created a table with a replication factor of
1, inserted some data before the swap. After the swap the data on nodes 2 and
3 is now missing.
One theory I have is that I am using different port numbers for the different
nodes, and I am only swapping the ip addresses and not the port numbers, so the
ip:port still looks unique
i.e. 127.0.0.2:9043 becomes 127.0.0.2:9044
and 127.0.0.3:9044 becomes 127.0.0.3:9043
