> I don't think this will matter on the long run for HBase 2, but at least in
> branch-1 and the current master we keep in multiple places copies of the
> region states in the master and this copies include information like the HRI.
> A problem that we have observed is when region replicas are being used and
> there is a split, the region replica from parent doesn't get collected from
> the region states and when the balancer tries to assign the old parent region
> replica, this will cause the RegionServer to create a new HRI with the
> details of the parent causing an inconstancy (see HBASE-18024).
