-----------------------------------------
Summary: Broker can not return to ISR because of
BadVersionException
Key: KAFKA-1407
URL: https://issues.apache.org/jira/browse/KAFKA-1407
Project: Kafka
Issue Type: Bug
Components: controller
Affects Versions: 0.8.1
Reporter: Dmitry Bugaychenko
Assignee: Neha Narkhede
Each morning we found a broker out of ISR at stuck with log full of messages:
{code}
INFO | jvm 1 | 2014/04/21 08:36:21 | [2014-04-21 09:36:21,907] ERROR
Conditional update of path /brokers/topics/topic2/partitions/1/state with data
{"controller_epoch":46,"leader":2,"version":1,"leader_epoch":38,"isr":[2]} and
expected version 53 failed due to
org.apache.zookeeper.KeeperException$BadVersionException: KeeperErrorCode =
BadVersion for /brokers/topics/topic2/partitions/1/state (kafka.utils.ZkUtils$)
INFO | jvm 1 | 2014/04/21 08:36:21 | [2014-04-21 09:36:21,907] INFO
Partition [topic2,1] on broker 2: Cached zkVersion [53] not equal to that in
zookeeper, skip updating ISR (kafka.cluster.Partition)
{code}
It seems that it can not recover after short netwrok break down and the only
way to return it is restart it using kill -9.
