Hi [~yangpoan] , I am getting the same exception while connecting controllers
dynamically. Also, I'm getting same metadata version while starting the KRaft
controllers.
INFO [ControllerRegistrationManager id=103 incarnation=I6MnwBhsRnGJlwIoGi7RTQ]
maybeSendControllerRegistration: cannot register yet because the
metadata.version is still 3.0-IV1, which does not support KIP-919 controller
registration. (kafka.server.ControllerRegistrationManager)
Kindly assist me to resolve this.
