Nick Dimiduk commented on HBASE-23969:
--------------------------------------
bq. Yes the wide-scrolling page seems good for this, and we can add the columns
selector as a follow-up effort.
(y)
bq. For the "server" column, I see there is an existing "ServerName" column
showing in Meta browser. Is that the same information already covered as
"server"?
This requires some code-reading. {{o.a.h.h.MetaTableAccessor}}, in the
{{hbase-client}} module, is the authority of reading meta's schema. It's
supported by constants defined in {{HConstants}}. {{MetaTableAccessor}} has a
lot going on because (1) region replicas were added in a backward-compatible
way, and (2) there are vestiges of code retained for reading schema from older
versions of HBase.

bq. The serverName column qualifier. Its the server where the region is
transitioning on, while column server is the server where the region is opened
on. They are the same when the region is in state OPEN.

> Assignee: Mingliang Liu
> Priority: Minor
>
> 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?
