> Key: KAFKA-911
> URL: https://issues.apache.org/jira/browse/KAFKA-911
> Project: Kafka
> Issue Type: Bug
> Components: controller
> Affects Versions: 0.8
> Reporter: Neha Narkhede
> Assignee: Neha Narkhede
> Priority: Blocker
> Labels: kafka-0.8, p1
>
> The controlled shutdown logic in the controller first tries to move the
> leaders from the broker being shutdown. Then it tries to remove the broker
> from the isr list. During that operation, it does not synchronize on the
> controllerLock. This causes a race condition while dispatching data using the
> controller's channel manager.
