[jira] [Created] (KAFKA-10807) AlterConfig should be validated by the target broker

Boyang Chen created KAFKA-10807:
-----------------------------------

             Summary: AlterConfig should be validated by the target broker
                 Key: KAFKA-10807
                 URL: https://issues.apache.org/jira/browse/KAFKA-10807
             Project: Kafka
          Issue Type: Sub-task
            Reporter: Boyang Chen


After forwarding is enabled, AlterConfigs will no longer be sent to the target broker. This behavior bypasses some important config change validations, such as path existence, static config conflict, or even worse when the target broker is offline, the propagated result does not reflect a true applied result. We should gather those necessary cases, and decide whether to actually handle the AlterConfig request firstly on the target broker, and then forward, in a validate-forward-apply path.
