stack commented on HBASE-10092:
-------------------------------

Unscheduling from 2.0.0 for now. My guess is that our users are not up for the 'surprise' of a new logging format, at least in 2.0.0 timeframe.

> Allows logging with less friction.  See http://logging.apache.org/log4j/2.x/  This rather radical transition can be done w/ minor change given they have an adapter for apache's logging, the one we use.  They also have and adapter for slf4j so we likely can remove at least some of the 4 versions of this module our dependencies make use of.
> I made a start in attached patch but am currently stuck in maven dependency resolve hell courtesy of our slf4j.  Fixing will take some concentration and a good net connection, an item I currently lack.  Other TODOs are that will need to fix our little log level setting jsp page -- will likely have to undo our use of hadoop's tool here -- and the config system changes a little.
> I will return to this project soon.  Will bring numbers.
