------------------------------
Summary: handle ZK session expiration properly when a new session
can't be established
Key: KAFKA-5473
URL: https://issues.apache.org/jira/browse/KAFKA-5473
Project: Kafka
Issue Type: Sub-task
Affects Versions: 0.9.0.0
Reporter: Jun Rao
In https://issues.apache.org/jira/browse/KAFKA-2405, we change the logic in
handling ZK session expiration a bit. If a new ZK session can't be established
after session expiration, we just log an error and continue. However, this can
leave the broker in a bad state since it's up, but not registered from the
controller's perspective. Replicas on this broker may never to be in sync.
