> Unnecessary controller warning : "Loaded ZK migration state of NONE"
> --------------------------------------------------------------------
>
> Key: KAFKA-16619
> URL: https://issues.apache.org/jira/browse/KAFKA-16619
> Project: Kafka
> Issue Type: Improvement
> Components: controller
> Affects Versions: 3.6.2
> Reporter: F Méthot
> Priority: Trivial
> Labels: good-first-issue
>
> When we launch a fresh cluster of Kafka and Kraft Controller, no zookeeper
> involved.
> We get this warning in the controller log:
> [2024-04-15 03:44:33,881] WARN [QuorumController id=3] Performing controller
> activation. Loaded ZK migration state of NONE.
> (org.apache.kafka.controller.QuorumController)
>
> Our project has no business with Zookeeper, seeing this message prompted us
> to investigate and spend time looking up this warning to find an explanation.
> We have that setting
> {_}zookeeper.metadata.migration.enable{_}=false
> and we still get that warning.
> In future version, to avoid further confusion this message should not be
> showed when zookeeper is not involved at all .
