[jira] [Created] (KAFKA-9359) Controller does not handle requests while broker is being shutdown

Lucas Bradstreet created KAFKA-9359:
---------------------------------------

             Summary: Controller does not handle requests while broker is being shutdown
                 Key: KAFKA-9359
                 URL: https://issues.apache.org/jira/browse/KAFKA-9359
             Project: Kafka
          Issue Type: Improvement
          Components: controller, core
            Reporter: Lucas Bradstreet


When a broker is shutdown it stops accepting requests, as it immediately socket server and handler pools are shutdown. It does so before shutting down the controller and or closing the log manager, and this may take some time to complete. During this time it will remain the controller as the zkClient has not been closed. We should improve the shutdown process such that a broker does not remain the controller while it is unable to accept requests that is expected of a controller.
