https://github.com/apache/zookeeper/pull/150
This feature is highly valuable for the community. It could solve the
problem of every team deploying Kafka on the cloud. Kafka has a static
configuration with the IP addresses of Zookeeper nodes. If you need to replace
these nodes and consequently change their IP addresses, you need to change
Kafka configuratino file and then restart all Kafka nodes so that they will
reload the updated configuration.
If this feature is merged, everyone deploying Kafka on the cloud could
configure it using a load balancer address, that would be re-resolved from time
to time, so that new Zookeeper instances would be automatically reachable from
Kafka without the need of restarts. This would greatly improve the availability
of Kafka.
Looking forward to have this merged.
