--------------------------------------

             Summary: Remove logback-related codepaths and configuration file
                 Key: FLINK-18829
                 URL: https://issues.apache.org/jira/browse/FLINK-18829
             Project: Flink
          Issue Type: Task
          Components: Deployment / Scripts, Runtime / Coordination
            Reporter: Robert Metzger


Flink currently (1.12-SNAPSHOT) provides support for two logging backends: Log4j2 (default) and logback.
The logback support is not really covered by our testing, and there's little evidence of widespread use.

Users can use a custom logging backend (as long as it's supported by slf4j) by providing the appropriate configuration files and jars in the classpath of all Flink services. Therefore, we should remove the logback-related files and codepaths in Flink and let our users set things up themselves.
