-----------------------------------
Summary: Reduce ignored package scope of KafkaAppender
Key: LOG4J2-3256
URL: https://issues.apache.org/jira/browse/LOG4J2-3256
Project: Log4j 2
Issue Type: Improvement
Reporter: Dongjin Lee
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.
