Appy commented on HBASE-10092:
------------------------------
+1
This has tackled many issues already. Let's get it in and work incrementally.
Great stuff [~balazs.meszaros]. Impressed. :)
On some of the previous things:
- Yeah i meant removing of the guards. That's one thing slf4j was promising.
But ignore it, too onerous and mechanical of a task to be done by single person
- bq.I did some verification, setting log levels still works through web ui.
Nice! forgot that one.
Just listing down remaining stuff for clarity (so doesn't get lost in extensive
discussion above):
- Update to log4j 2 backend
- Fix transitive include from hadoop
> Move up on to log4j2

> 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.
