-----------------------------------
Summary: AbstractConfig.logUnused() may log confusing warning
information.
Key: KAFKA-5834
URL: https://issues.apache.org/jira/browse/KAFKA-5834
Project: Kafka
Issue Type: Bug
Components: log
Reporter: Jiangjie Qin
Fix For: 1.0.0
Currently {{AbstractConfig.logUnused()}} logs unused configurations in at WARN
level. It is a little weird because as long as there is a configurable class
taking a configuration, that configuration will be logged as unused at WARN
level even if it is actually used. It seems better to make it an INFO level
logging instead, or maybe it can take a log level argument to allow caller to
decide which log level should be used.
