---------------------------------------
Thanks [~ndimiduk]!
I brows the code quickly and think the "ServerName" information in table.jsp
now is actually
[using|https://github.com/apache/hbase/blob/eface7440722e4e85f7848cdbc1f975f4785f334/hbase-client/src/main/java/org/apache/hadoop/hbase/MetaTableAccessor.java#L952]
the "info:server" column in meta table. We here need to include the "info:sn"
information. When we show it in table.jsp, can we call it
"TransitioningOnServerName", or is there a better name? Alternatively, we can
simply rename the existing "ServerName" column in table.jsp as "server" and
this new column as "sn". This seems not very descriptive though.
For the merge/mergeA/mergeB, I see we now support merging multiple regions, and
the number can be more than 2. The old "mergeA" and "mergeB" are now deprecated
in favor of "merge0000" and "merge0001. So I'm thinking this meta browser shows
the "merge*" values as a single string in the "MergeRegionName" column of the
table in table.jsp. Is this a good idea? This way we don't need dynamic columns
in table.jsp. I guess user cares about the parent regions than the column name
in "hbase:meta" table, be it "mergeA" or "merge0000".
Last, is the sequence number during open required? We can add that as well
since it's already in location information.
I have a basic patch, and attach the screenshot here. It enables X-scroll and
disables the wrap for long text.

> 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?
