-----------------------------------
Summary: KIP-817: Fix inconsistency in dynamic application log
levels
Key: KAFKA-13625
URL: https://issues.apache.org/jira/browse/KAFKA-13625
Project: Kafka
Issue Type: Improvement
Components: core
Reporter: Dongjin Lee
Assignee: Dongjin Lee
As of present, there are two ways of changing log levels in Runtime:
# JMX API
# Admin API
However, there are some inconsistencies between these two ways;
# JMX API allows OFF level; but Admin API does not. If the user tries to set
the logger's level to OFF, Kafka responds with INVALID_CONFIG (40) error.
# JMX API converts unsupported log level to DEBUG; but Admin API throws an
error. The documentation does not state this difference in semantics.
To fix these inconsistencies, we have to:
# Add OFF level to LogLevelConfig.
# Add documentation on different semantics between JMX and Admin API.
