---------------------------------------
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.
