chunhui shen commented on HBASE-8251:
-------------------------------------

bq.3) Enable SSH for ROOT only not others
How about if ROOT and META are on the same regionserver?

> 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.
