Description

Flink is using slf4j as the logging interface and log4j as the logging backend.
I got requests from users which want to use a different logging backend (logback) with Flink. Currently, its quite hard for them, because they have to do a custom Flink build with log4j excluded.

The purpose of this JIRA is to ship a Flink build that is prepared for users to use a different logging backend.
I'm also going to document how to use logback with Flink.
