      Description

      Currently, there is a case in CatalogJanitor which checks if the default region info is missing in metaRow, it is reporting it as EmptyRegionInfoList. 

       

      For read replica, this entry needs to be dealt with. In hbase-1, this was caused by region server opens an orphan replica region. In hbase-2, it will not happen since checks are added to defend this case. The hback2 fix is still needed for upgrade. Issues could be brought into hbase-2 post upgrade, hbck2 needs to handle it.
