Jieshan Bean commented on HBASE-8251:
-------------------------------------
bq.*, currentMetaServer is marked dead by master. Then we still have two
possible places to assign meta.
This RS should belong to the set of ServerManager#onlineServers just before
marking it as dead(See the related code of ServerManager#onlineServers and
DeadServer#processingDeadServers.
). So the below check returns true:
{code}
this.serverManager
.isOnlineOrProcessingDeadServer(currentMetaServer).
{code}
So needToAssign is false. No new assign would happen under this scenario.
Correct me if I misunderstood you:). Thank you.
> enable SSH before assign META on Master startup

> I think HBASE-5918 could not fix this issue. In HMaster#assignRootAndMeta:
> 1. Assign ROOT.
> 2. Block until ROOT be opened.
> 3. Assign META.
> 4. Block until META be opened.
> SSH is enabled after step 4. So if the RS who host ROOT dies before step 4,
> master will be blocked.
