------------------------------------
Summary: Switch to Log4j 2 by default
Key: FLINK-15672
URL: https://issues.apache.org/jira/browse/FLINK-15672
Project: Flink
Issue Type: Improvement
Components: Build System
Reporter: Stephan Ewen
Log4j 1.x is outdated and has multiple problems:
* No dynamic adjustments of Log Level
* Problems with newer Java Versions
* Not actively developed any more
Switching to Log4J 2 by default would solve this.
