Description

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.
