             Summary: Validate config inter-dependencies for KafkaConfig only after dynamic configs are loaded
                 Key: KAFKA-9096
                 URL: https://issues.apache.org/jira/browse/KAFKA-9096
             Project: Kafka
          Issue Type: Improvement
          Components: core
            Reporter: Rajini Sivaram
            Assignee: Rajini Sivaram
             Fix For: 2.5.0


We currently perform all validations in KafkaConfig when creating the config instance. This includes some checks that include multiple configs, e.g. is the inter-broker listener also present in the listener map? With dynamic configs, some configs come from the static properties file and others come from ZooKeeper. At the moment, we have a requirement for the static properties file to be consistent on its own, even though the config we actually use for the broker is the one where we have overlayed the configs from ZK on top of the static configs. We should continue to validate individual configs for the static configs file, but delay validating inter-dependencies until dynamic configs have also been processed.
