Brandon Williams commented on CASSANDRA-16718:
----------------------------------------------
There are a couple of tests that are now too synthetic to pass like the
EC2SnitchTest.testEc2MRSnitch and OutboundConnectionsTest.reconnectWithNewIp
since both try to pass an arbitrary IP address to reconnect to, where now only
the live gossip value is used. I'm not sure it's worth fleshing those into
more thorough tests like the dtest in the patch that covers this.
> Changing listen_address with prefer_local may lead to issues

> Key: CASSANDRA-16718
> URL: https://issues.apache.org/jira/browse/CASSANDRA-16718
> Project: Cassandra
> Issue Type: Bug
> Components: Local/Config
> Reporter: Jan Karlsson
> Assignee: Brandon Williams
> Priority: Normal
> Fix For: 3.11.x, 4.0.x
>
>
> Many container based solution function by assigning new listen_addresses when
> nodes are stopped. Changing the listen_address is usually as simple as
> turning off the node and changing the yaml file.
> However, if prefer_local is enabled, I observed that nodes were unable to
> join the cluster and fail with 'Unable to gossip with any seeds'.
> Trace shows that the changing node will try to communicate with the existing
> node but the response is never received. I assume it is because the existing
> node attempts to communicate with the local address during the shadow round.
