David Glasser commented on KAFKA-4041:
--------------------------------------
I think this should be reopened, because I think the eventually-merged
KAFKA-5473 fix did not actually implement the ZooKeeper-re-creation logic. (At
the very least, I know experimentally that Kafka 1.1 does not fix this bug.)
> kafka unable to reconnect to zookeeper behind an ELB
> ----------------------------------------------------
>
> Key: KAFKA-4041
> URL: https://issues.apache.org/jira/browse/KAFKA-4041
> Project: Kafka
> Issue Type: Bug
> Affects Versions: 0.9.0.1, 0.10.0.1
> Environment: RHEL EC2 instances
> Reporter: prabhakar
> Priority: Blocker
>
> Kafka brokers are unable to connect to zookeeper which is behind an ELB.
> Kafka is using zkClient which is caching the IP address of zookeeper and
> even when there is a change in the IP for zookeeper it is using the Old
> zookeeper IP.
> The server.properties has a DNS name. Ideally kafka should resolve the IP
> using the DNS in case of any failures connecting to the broker.
