Yuki Morishita commented on CASSANDRA-8735:
-------------------------------------------
So the patch will make
{{BatchlogEndpointFilterTest#shouldSelectTwoFirstHostsFromSingleOtherRack}}
fail occasionally since the test is expected to be always the first two.
[~mishail] is this intended behavior? I saw the case where the same 2 nodes
always getting a lot of batch log traffic.
> Batch log replication is not randomized when there are only 2 racks
