-----------------------------------
Summary: Bug in controlled shutdown logic in controller leads to
controller not sending out some state change request
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
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.
