Describe the bug (actual behavior)

Hi. I created 3 kafka brokers. In "Brokers" section, I can see "Active Controller" with a value 2. However, in the list of brokers below, I can see a green 'tick' mark next to broker ID 3. When I move a curson on this tick, I can read "Active Controller".

I checked the logs on each broker. I can read there following: broker1: DEBUG [Controller id=1] Broker 2 has been elected as the controller, so stopping the election process. broker2: INFO [Controller id=2] 2 successfully elected as the controller. broker3: DEBUG [Controller id=3] Broker 2 has been elected as the controller, so stopping the election process.

So the active one is 2. That means that tick mark next to broker id 3 is wrong. (Or it's me that I can't get something here)

All best, Chris

Expected behavior

Green tick mark should be next to broker id 2

Hi, please take a look on this

It`s surely a bug in 0.7.1. And has been fixed in master branch. But also exist another bug as the activeController node is not the correct one when the cluster is running on kraft. I have commited a pr on this problem.

I have reviewed the PR code you submitted and noticed that you obtained the correct active controller id for the KRaft mode deployment via JMX. In the master branch implementation, it seemed to be obtained directly through Java's kafka-clients, but it would get active controlelr id from the broker nodes, similar to the way the active controller is obtained in a Zookeeper-deployed mode.
