> 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.
