stack commented on HBASE-8645:
------------------------------
The SeverName.toShortString drops the startcode and intentionally makes a
String that does not look like a ServerName#toString, rather it is a host+port
only host is missing domain. Here is sample of what logging looks like now:

> No need of dragging around domain part of a hostname when we make
> ServerNames. Rather than do a.example.org,60000,12345 as we currently do,
> just output: 1,60000,12345. This will make names displayed in UI and or shell
> smaller. Will also tighten up our logs a little, especially where ServerName
> is part of a thrad name.
