> The situation can appear in following steps in release hbase1.2.6
> 1. create 'testtable', 'info', {REGION_REPLICATION=>2}
> 2. write somerecords into 'testtable'
> 3. split the table 'testtable'
> 4. after the spliting, the serverHoldings in RegionStates still holds the regioninfo for the replica of parent region
> 5. restart the regionserver where the parent replica-region located
> 6. the offlined replica of parent region will be assigned in ServerCrashProcedure.
