Hi!

The bundled log4j version (1.x) does not support that.

But you can replace the logging jars with those of a different framework
(like log4j 2.x), which supports changing the configuration without
stopping the application.
You don't need to rebuild flink, simply replace two jars in the "lib"
folder (and update the config file, because log4j 2.x has a different
config format).

This guide shows how to swap log4j 1.x for logback, and you should be able
to swap in log4j 2.x in the exact same way.
