Daniel Cranford commented on CASSANDRA-8735:
--------------------------------------------
Looks like it was reverted/overwritten (seemingly unintentionally) by the fix
for CASSANDRA-7237
We've seen this in production with Cassandra 3.9. One or two rack DCs always
select the same two hosts for batch log replication.
> Batch log replication is not randomized when there are only 2 racks
