-----------------------------------
Summary: Add pluggable logging framework support
Key: KAFKA-13604
URL: https://issues.apache.org/jira/browse/KAFKA-13604
Project: Kafka
Issue Type: Improvement
Components: core, KafkaConnect
Reporter: Dongjin Lee
Assignee: Dongjin Lee

thread|https://lists.apache.org/thread/xwgt8ydvnvnqwvhpq2cobgb5wk5mg52t]
As of present, Apache Kafka is using log4j 1.x and planning to migrate into
log4j 2.x. Dislike Kafka Streams, it calls log4j's API directly, making it hard
for the users to replace the logging framework - also making Kafka vulnerable
to log4j's security vulnerabilities.
Apache Kafka (with Connect) is calling log4j's API directly to support the
dynamic logger level change feature; SLF4j does not support this feature yet,
but [they are planning to support this|https://jira.qos.ch/browse/SLF4J-124] in
the near future.
Supporting the pluggable logging framework by using SLF4j as a facade will
allow the users to change the actual logging framework, reducing security
problems freely.
