Hi TaiWuJu, Thanks for the KIP. I think this is very helpful for Kafka developers working with the Kafka protocol.
AS1: Trying out the PR, I notice that the tool uses DESCRIBE_CLUSTER to talk to controllers, but it uses METADATA to talk to brokers. Since both brokers and controllers support DESCRIBE_CLUSTER in recent releases, I wonder whether you could also use DESCRIBE_CLUSTER If available with brokers too. The advantage is that the error handling when using --bootstrap-server with a controller is much nicer.
