URL: https://issues.apache.org/jira/browse/KAFKA-16163
Project: Kafka
Issue Type: Bug
Affects Versions: 3.7.0
Reporter: Mickael Maison
When starting a single node in combined mode:
{noformat}
$ KAFKA_CLUSTER_ID="$(bin/kafka-storage.sh random-uuid)"
$ bin/kafka-storage.sh format -t $KAFKA_CLUSTER_ID -c
config/kraft/server.properties
$ bin/kafka-server-start.sh config/kraft/server.properties{noformat}
it's constantly spamming the logs with:
