Description

Kafka ships with default ZK configuration. With the upgrade to ZK 3.5, our defaults include running ZK's AdminServer on port 8080. This is an unfortunate default as it tends to cause conflicts.

I suggest we default to disable ZK's AdminServer in the default ZK configs that we ship. Users who want to use AdminServer can enable it and set the port to something that works for them. Realistically, in most production environments, a different ZK server will be used anyway. So this is mostly to save new users who are trying Kafka on their own machine from running into accidental and frustrating port conflicts.
