Subject [jira] [Commented] (ACCUMULO-2373) Daemons should be able to log if specifies sufficient logging
Date Tue, 18 Feb 2014 03:29:19 GMT


Josh Elser commented on ACCUMULO-2373:

I think (at least) two issues here are getting conflated.

The fix for when no matching {{*_logger.xml}} is present, we probably don't need to start
the thread which I think would fix the issue your raised. I'm not sure if Log4j's file watchdog
code is smart enough to pick up logging if it wasn't present at the beginning -- need to test

[~vickyuec], I feel like you're more concerned about Log4j configuration not working as you
want it to  (all of logging configured using any of the facilities that log4j provides) --
Accumulo has never worked this way. That's not to say it shouldn't, but that's not the focus
here. As it stands, for Accumulo to work as a whole, it *requires* this specific configuration
(the *_logger.xml files) to work as intended.

Additionally, the ability to configure logging frameworks other than Log4j is also currently
out of the scope of Accumulo, but, again, this is something that should be addressed if you
have specific needs/wants that are presently not functional.

All my daemons have this as the last line of their logs:

> {noformat}
> Note that I don't use generic_logger.xml, and this wasn't a requirement for 1.4. But
now it seems there is no logging if *_logger.xml files are not present (as ACCUMULO-2349 has
also reported).
