-------------------------------
Summary: Unexpected exception in zookeeper
Key: ZOOKEEPER-3036
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3036
Project: ZooKeeper
Issue Type: Bug
Components: jmx
Affects Versions: 3.4.10
Environment: 3 Zookeepers, 5 kafka servers
Reporter: Oded
We got an issue with one of the zookeeprs (Leader), causing the entire kafka
cluster to fail:
2018-05-09 02:29:01,730 [myid:3] - ERROR
[LearnerHandler-/192.168.0.91:42490:LearnerHandler@648] - Unexpected exception
causing shutdown while sock still open

[LearnerHandler-/192.168.0.91:42490:LearnerHandler@661] - ******* GOODBYE
/192.168.0.91:42490 ********
We would expect that zookeeper will choose another Leader and the Kafka cluster
will continue to work as expected, but that was not the case.
