> As of present, KafkaAppender ignores logging messages from the loggers starting with "org.apache.kafka". This is because KafkaAppender uses KafkaPoducer internally and to avoid recursive logging.
> However, the current ignored package scope, "org.apache.kafka", is too large, since KafkaProducer uses "org.apache.kafka.common" and "org.apache.kafka.client" only. It is problematic when Apache Kafka uses log4j2 for its logging.
> As of present, Apache Kafka is still using log4j 1.x, but a migration project is under-progress:
>  * KAFKA-9366
>  * KAFKA-12399
> If this project is taken, Apache Kafka will deprecate its log4j-appender and migrate into log4j2's KafkaAppender. Reducing the ignored package scope is a prior task to this work.
