Jeffrey Zhong commented on HBASE-8251:
--------------------------------------
[~rajesh23] brought me attention to this JIRA. Basically I saw similar issue
during test against the patch for bhase-7824. The solution I'm using for the
issue is that
2) Assign ROOT
3) Enable SSH for ROOT only not others
4) Assign META
5) Enable SSH globally
The above solution is less intrusive. The existing patch for the JIRA might
also have double assignment issue because meta assignment could happen in both
places: master initialization and META SSH.
Please let me know what you think.
Thanks,
-Jeffrey

> 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.
