Enis Soztutar commented on HBASE-11261:
---------------------------------------
The initial plan was to have the daughters refer to the parent replica until
their own split is complete, so that during the split, read availability is not
affected since the readers can go to the replica regions to read while the
region is still splitting. However, as per above, that seemed too-complex to
keep references around, especially fixing these kind of edge-cases would be
pretty hard for HBCK, so I think we have simplified the approach. When a split
happens, meta is updated with entries about split daughter replicas, but as far
as I remember, there was not reason to do further changes in CJ for this.
