F Méthot updated KAFKA-16619:
-----------------------------
Description:
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 .
