Hi all, @Ismael
As I stated in the KIP (see subsection 2 of 'Motivation'), the log4j community's implementation can't be an alternative for the existing 'log4j-appender' users since their message format is different, breaking the related, already running pipelines. Add to this, the log4j appender can be best maintained when log4j2 and Kafka versions are updated together. (see subsection 1 of 'Motivation'.) @Israel Then, you mean instead of creating a new artifact ('log4j2-appender'), just substituting the traditional artifact ('log4j-appender') with a new implementation would be better. Do I understand correctly? After all, one main reason I hurried this proposal is that for the VerifiableLog4jAppender tool, we can't entirely remove log4j 1.x artifact from the classpath - making classpath logic more complex. (see here <https://github.com/apache/kafka/pull/7898/commits/f56f491e68ef2a976c0e3331a48dd881b74a06b3> for KIP-653 <https://cwiki.apache.org/confluence/display/KAFKA/KIP-653%3A+Upgrade+log4j+to+log4j2> and here <https://github.com/apache/kafka/pull/10244/commits/b66fce3d04e005b1eaeae006d78bd8e698f417c6> for KIP-719 <https://cwiki.apache.org/confluence/display/KAFKA/KIP-719%3A+Add+Log4J2+Appender> .) @Boojapho, @Konstantine Thanks for the voting.
