> Dtests with multi-dc setups don't update the topology properties file of a newly joining node post cluster creation.
> The new node will join dc1 but it's snitch will report the default snitch config == dc1 == all nodes are in dc1 == there are no other dcs. That leads to bootstrap, token, startup,... problems.
> Solution: When a new node is created in dtests check for existing dcs. If there are any update the topology file.
