Marcus Eriksson updated CASSANDRA-14610:
----------------------------------------
Status: Patch Available (was: Open)
the test depends on hard coded cassandra version and the order in which
keyspaces/datacenters are listed, this should fix those things;
https://github.com/krummas/cassandra-dtest/commits/marcuse/14610
https://circleci.com/workflow-run/6c0f0d61-3b5c-49dd-bdeb-22d24dc60b15
it also reduces the number of nodes started to 4 since starting 6 nodes is
likely to fail in circle ci
