Jonathan Ellis commented on CASSANDRA-6551:
-------------------------------------------
v2 attached that does some cleanup (leave return type Collection so we don't
need to copy into Lists unnecessarily) and restores randomness of endpoints per
rack.
The randomness breaks the hardcoded tests so I'm going to throw it back to you
to figure out what to do about that. :)

> Right now the batchlog replication code just randomly picks 2 other nodes in
> the same DC, regardless of rack. Ideally we'd pick 2 replicas in other racks
> to achieve higher fault tolerance.
