Edward Sargisson updated FLUME-2050:
------------------------------------
Attachment: FLUME-2050.patch
Patch for Flume using log4j2. Largest area of change was TestSyslogUdpSource.
Note that we should wait for log4j2 to go to GA before doing this upgrade and
thus I will not create a review board for it yet. I'm uploading this patch so
that it's ready to go and in case somebody needs it.

> Log4j1 is being abandoned in favour of log4j2. Log4j2, by all that I've seen,
> has better concurrency handling and the Log4j2 FlumeAppender is nice (easily
> configurable, 3 different styles of agents).
> Log4j1 has a concurrency defect which means that rolling over a log file into
> a directory for the Flume spool directory source will not be reliable. Log4j2
> has fixed this.
> Alternatively the log4j2 FlumeAppender may allow Flume to log its own logs
> via itself.
