[jira] [Commented] (KAFKA-1887) controller error message on
shutting the last broker
[ https://issues.apache.org/jira/browse/KAFKA-1887?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14284502#comment-14284502 ]
Jun Rao commented on KAFKA-1887:
--------------------------------
When shutting down the broker, we unregister the broker from ZK first, followed by shutting down the controller. It seems that we should be shutting down the controller first.
