Xiaomin Zhang created KAFKA-3386:
------------------------------------
Summary: Need to log "Rejected connection" as WARNING message
Key: KAFKA-3386
URL: https://issues.apache.org/jira/browse/KAFKA-3386
Project: Kafka
Issue Type: Improvement
Reporter: Xiaomin Zhang
Priority: Minor
We may found below INFO messages in the log due to inappropriate configuration:
INFO kafka.network. Acceptor: Rejected connection from /XXXX, address already
has the configured maximum of 10 connections.
It will make more sense for Kafka to report above message as "WARN", not just
"INFO", as it truly indicates something need to check against.
