> Right after a region split but before the daughter regions are compacted, we
> have two daughter regions containing Reference files to the parent hfiles.
> If we take snapshot right at the moment, the snapshot will succeed, but it
> will only contain the daughter Reference files. Since there is no hold on the
> parent hfiles, they will be deleted by the HFile Cleaner after they are no
> longer needed by the daughter regions soon after.
> A minimum we need to do is the keep these parent hfiles from being deleted.
