huaxiang sun updated HBASE-18625:
---------------------------------
Attachment: HBASE-18625-branch-1-v001.patch
Attach the patch for branch-1 first. Will update with an unitest and patch for
master branch later.
The root cause is that when replica parent is offlined, its state is not SPLIT
and this does not trigger it to be removed from removeFromServerHoldings.
> Splitting of region with replica, doesn't update region list in
> serverHolding. A server crash leads to overlap.

> 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.
