Subject [jira] [Commented] (HBASE-10092) Move up on to log4j2
Date Thu, 27 Jul 2017 19:02:01 GMT

    [ https://issues.apache.org/jira/browse/HBASE-10092?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16103710#comment-16103710
] 

Mikael Ståldal commented on HBASE-10092:
----------------------------------------

Yes, we have not made much progress recently on supporting Log4j 1.x config files. We have
partial support, but it may not be very useful in practice. Full support would require some
more work, and none of the core developers have prioritized that recently.

We will soon make a new release (2.9) but it will most likely not contain this.

> 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.
