Yeah, thanks for above specific explanations which all make sense in my
opinion. I just want to confirm whether there are other implicit rules in
community. :)
I already submitted the hotfix commit for addressing previous comments, then
i would submit another pr for rename issue.

> Affects Versions: 1.8.0
> Reporter: zhijiang

>
> _The current {{RebalancePartitioner}} implementation seems a little hacky for
> selecting a random number as the first channel index, and the following
> selections based on this random index in round-robin fashion._
> _Especially for the corner case of {{numChannels = Integer.MAX_VALUE}}, it
> would trigger next random index once reaching the last channel index.
> Actually the random index should be selected only once at the first time._
