I know logback and log4j2 can do this. Flume is shipped with log4j 1.2 but in theory nothing prevents you to use a different backend for logging. It is not guaranteed that it will work in practice, but it may worth a try. http://logback.qos.ch/manual/configuration.html#autoScan https://logging.apache.org/log4j/2.x/manual/configuration.html (search for "automatic reconfiguration")
Laxman's finding is correct but it will possibly add a code binding on a particular logger backend. It has benefits and downsides so worth discussing. I would rather investigate in upgrading to log4j2 because log4j 1.x reached end of life. Cheers, Attila On 2016.
