Nick Dimiduk commented on HBASE-23969:
--------------------------------------

bq. I brows the code quickly and think the "ServerName" information in 
table.jsp now is actually using the "info:server" column in meta table. We here 
need to include the "info:sn" information...

Oh no! I have them backwards then :( I guess we missed that in reviews. How 
about "target server name" or something involving the word "destination"? It is 
the target or destination of a current move operation.

bq. For the merge/mergeA/mergeB, I see we now support merging multiple regions, 
and the number can be more than 2...

Nice observation. I think the view should support rendering all the column 
qualifiers that the underlying code knows how to handle. For instance, if this 
version of HBase can support reading the old meta format column qualifiers and 
the new, view should be able to render both. Maybe there's a single "merge 
targets" column that has a newline-delimited list of server names? That way the 
table grows tall with additional merge members, instead of impossibly wide.

bq. is the sequence number during open required?

I don't know. Do you have any operators around, folk who might be using this to 
diagnose issues? I'm leaning toward yes, just because it's available and the 
purpose of the view is to make the content of meta more accessible.

[~stack], [~clayb], [~elserj], [~tychang] -- any comments here with your 
operators hats on?

> The Meta table browser lists region states. There are other {{info}} columns 
> in the table, which should be displayed. Looking through {{HConstants}}, it 
> seems we need to add the following:
>  * {{server}}
>  * {{sn}}
>  * {{splitA}}
>  * {{splitB}}
>  * {{merge}}
>  * {{mergeA}}
>  * {{mergeB}}
> Are there others?
