--------------------------------------
@Ramkrishna
yes, ideally that is the case. But we may end up with this, if for example, the
regions are non-uniform. I think we still have to prioritize the ref files in
compaction, since they also prevent splitting further.
> META entries from daughters can be deleted before parent entries

> HBASE-5986 fixed and issue, where the client sees the META entry for the
> parent, but not the children. However, after the fix, we have seen the
> following issue in tests:
> Region A is split to -> B, C
> Region B is split to -> D, E
> After some time, META entry for B is deleted since it is not needed anymore,
> but META entry for Region A stays in META (C still refers it). In this case,
> the client throws RegionOfflineException for B.
