Stefania commented on CASSANDRA-10243:
--------------------------------------
So far I've done {{GossipingPropertyFileSnitch}} and {{PropertyFileSnith}} in
2.1. Here is what the error looks like:
{code}
ERROR 09:51:55 Cannot update data center or rack from [DC1, RAC1] to [DC2,
RAC2] for live host /127.0.0.1, property file NOT RELOADED
{code}
cc [~jbellis] and [~tjake] regarding the two questions above and summarized
here:
* Should we enhance the deprecated snitch {{YamlFileNetworkTopologySnitch}}
which is available in 2.1 only
* Should we allow a node to join the cluster when the rack changes on startup
> Warn or fail when changing cluster topology live
