Jun Rao created KAFKA-928:
-----------------------------
Summary: new topics may not be processed after ZK session
expiration in controller
Key: KAFKA-928
URL: https://issues.apache.org/jira/browse/KAFKA-928
Project: Kafka
Issue Type: Bug
Components: core
Affects Versions: 0.8
Reporter: Jun Rao
Priority: Blocker
When controller loses its ZK session, it calls partitionStateMachine.shutdown
in SessionExpirationListener, which marks the partitionStateMachine as down.
However, when the controller regains its controllership, it doesn't mark
partitionStateMachine as up. In TopicChangeListener, we only process new topics
if the partitionStateMachine is marked up.
