--------------------------------------

             Summary: the effective kraft version of `--no-initial-controllers` should be 1 rather than 0
                 Key: KAFKA-18028
                 URL: https://issues.apache.org/jira/browse/KAFKA-18028
             Project: Kafka
          Issue Type: Bug
            Reporter: Chia-Ping Tsai
            Assignee: Chia-Ping Tsai


`hasDynamicQuorum`  only considers the `initialControllers` [0], which is configured when either `initial-controllers` or `standalone` is specified. It will result in the following unexpected behaviors:

1. Using the `no-initial-controllers` configuration get `kraft.version=0`
2. This leads to a command error when executing `no-initial-controllers --feature kraft.version=1`

{quote}
Cannot set kraft.version to 1 unless KIP-853 configuration is present. Try removing the --feature flag for kraft.version.

This issue is minor because no record is written for no-initial-controllers.
