[~iamaleksey] Great, I didn't see any activity yet on CASSANDRA-12844, so I 
attached a patch there.

[~daniel.cranford] [~yukim] I think CASSANDRA-12884 (unresolved) covers the 
issue - whatever the origin of it was.

I don't remember doing this on purpose, it looks like a bad merge.

Pinging [~blambov] and [~iamaleksey].
As Daniel pointed above, CASSANDRA-7237 removed randomizing part in 3.0+ 
(https://github.com/apache/cassandra/commit/762db474273f764b189d3613fce33943cd64701b#diff-642bb5d5ca328b50d59f2a550c94e5edR533).
I cannot tell it was intentional or not, so can you take a look and see if it 
still need to be patched by this? Thanks.

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.

Hi, I'm not seeing this patch in trunk or latest 3.0.X, is it reverted or 
overwritten in some version? Thanks.

[~yukim]. I don't remember. It looks like I made that test case based on the 
assumption that the behavior from Jonathan's patch CASSANDRA-6551 #2 *is* the 
expected one.

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.
