After the scale down and up procedure, there seems to be a leftover reference to a draining broker pod that isn't reachable anymore.
The log is flooded with UnknownHost exception with reference to broker-1 that was actually a draining pod.
I've tried to collect logs from all phases.
From the broker-0 logs it can be observed that despite the UnknowHost exception after scale-up new cluster connection is formed successfully. However, it's hard to spot from e.g. tailing a log via oc logs -f.
There're broker-1 logs from before, int, after phase (before scale down, intermediate draining, after scale up).
Notice that after scale up broker-1 reports 2 cluster connections instead of 1.
