Hi Berthold, Thanks for your interest in this issue. I am the person who is working on this issue with KIP-653 and KIP-719.
- KIP-653: https://cwiki.apache.org/confluence/display/KAFKA/KIP-653%3A+Upgrade+log4j+to+log4j2 - KIP-719: https://cwiki.apache.org/confluence/display/KAFKA/KIP-719%3A+Deprecate+Log4J+Appender As of present, there is no explicit plan to upgrade to log4j2 yet. I hope this feature is adopted in 3.2.0 but can't be sure yet. If you are urgent about this functionality, you can have a try on a preview based on Apache Kafka 3.0.0 here: http://home.apache.org/~dongjin/post/apache-kafka-log4j2-support/ (I will release a 3.1.0 based on as soon as the official version is released.)
