stack commented on HBASE-8629:
------------------------------
This is a useful formatting page:
http://www.tutorialspoint.com/log4j/log4j_patternlayout.htm
While we are in here, we should upgrade? Anyone w/ experience on log4j 2? I do
not see it in a repo.

> + Our thread names are nice and descriptive and are useful particularly when
> running standlone mode but it gets silly printing out full thread names when
> distributed on each log (we could turn off printing thread name but can be
> helpful).
> + Do we have to print the fully qualified path for all files every time?
> Lines get really long and hard to read. Ditto for region names.
> + Can we print out just the class name rather than full package qualified
> class name.

> + Some logging is bound to freak operators. We print out the full stack
