Paulo Motta commented on CASSANDRA-10243:
-----------------------------------------
[~Stefania] After CASSANDRA-9474 is merged, the rack startup failure message
will change to {{Cannot start node if snitch's rack (rack2) differs from
previous rack (rack1). Please fix the snitch configuration, decommission and
rebootstrap this node or use the flag -Dcassandra.ignore_rack=true}}, can you
please update that on
{{replication_test.py:SnitchConfigurationUpdateTest.test_cannot_restart_with_different_rack}}
before submitting the PR? Thanks!
> Warn or fail when changing cluster topology live
