-------------------------------------------
Summary: `generatetokens` uses the wrong allocation strategy
Key: CASSANDRA-18093
URL: https://issues.apache.org/jira/browse/CASSANDRA-18093
Project: Cassandra
Issue Type: Bug
Reporter: Branimir Lambov
When the number of racks is the same as the replication factor, token
allocation should use `NoReplicationTokenAllocator`. Because `generatetokens`
caches the allocation strategy
[here|https://github.com/apache/cassandra/commit/2346ed8241022882e77433e283ab8ce3004d12b0#diff-a93e5fa817f4b6d64484e0c28391b76e1760f51860de7f4f036470766ff5090cR225],
it uses one that was created before all the racks are defined and does not
switch to the correct one.
This has the effect of constructing very poor allocations for the racks = RF
case, especially for the first couple of nodes.
