------------------------------------------------
[~Apache9]
Thanks for the comments. I have pushed an addendum addressing your comments on
RB. for branch-2.1 the current patch does not work as the code base is
different. Will prepare one and upload here before committing.
I have also pushed the fix to branch-2.

> Generally it is better that the parent region when split creates the daughter
> region in the same target server.
> But for replicas also we do the same and all the replica regions are created
> in the same target server. We should ideally be doing a round robin and only
> the primary daughter region should be opened in the intended target server
> (where the parent was previously opened).
> [~huaxiang] FYI.
