Onur Karaman updated KAFKA-4410:
--------------------------------
Description:
We expect KafkaController to send the broker undergoing controlled shutdown one
StopReplicaRequest for each follower replica on that broker. Examining
KafkaController.shutdownBroker, we see that this is not the case:
1. KafkaController.shutdownBroker itself sends the shutting down broker a
StopReplicaRequest for each follower replica
2. KafkaController.shutdownBroker transitions every follower replica to
OfflineReplica in its call to replicaStateMachine.handleStateChanges, which
also sends the shutting down broker a StopReplicaRequest.
