> The problem is in the testNoFallback:
> Let's say we have 11 nodes (from parameter) and we would like to choose 5
> nodes (hard coded in the test).
> As the first two replicas are chosen from the same rack an all the other from
> different racks it's not possible, so we except a failure.
> But we have an assertion that the success count is at least 3. But this is
> true only if the first two replicas are placed to the rack1 (5 nodes) or
> rack2 (5nodes). If the replica is placed to the rack3 (one node) it will fail
> immediately:
>
> Lucky case when we have success count > 3
> {code:java}
> rack1 -- node1
> rack1 -- node2 -- FIRST replica
> rack1 -- node3 -- SECOND replica
> rack1 -- node4
> rack1 -- node5
> rack2 -- node6
> rack2 -- node7 -- THIRD replica
> rack2 -- node8
> rack2 -- node9
> rack2 -- node10
> rack3 -- node11 -- FOURTH replica{code}
> The specific case when we have success count == 1, as we can't choose the
> second replica on rack3 (This is when the test is failing)
> {code:java}
> rack1 -- node1
> rack1 -- node2
> rack1 -- node3
> rack1 -- node4
> rack1 -- node5
> rack2 -- node6
> rack2 -- node7
> rack2 -- node8
> rack2 -- node9
> rack2 -- node10
> rack3 -- node11 -- FIRST replica{code}
