      Description

      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.
