----------------------------------
Summary: updateIsr should stop after failed several times due to
zkVersion issue
Key: KAFKA-3042
URL: https://issues.apache.org/jira/browse/KAFKA-3042
Project: Kafka
Issue Type: Improvement
Affects Versions: 0.8.2.1
Environment: jdk 1.7
centos 6.4
Reporter: Jiahongchao
sometimes one broker may repeatly log
"Cached zkVersion 54 not equal to that in zookeeper, skip updating ISR"
I think this is because the broker consider itself as the leader in fact it's a
follower.
So after several failed tries, it need to find out who is the leader
