> Key: KAFKA-8057
> URL: https://issues.apache.org/jira/browse/KAFKA-8057
> Project: Kafka
> Issue Type: Bug
> Components: producer
> Affects Versions: 2.1.0
> Reporter: Bolke de Bruin
> Priority: Critical
> Fix For: 2.1.1
>
>
> Producers, contrary to brokers, retain the IPs of brokers instead of
> resolving the Hostname again. This stops producers from connecting to the
> brokers.
> To reproduce have a producer connect to brokers, bring down the brokers and
> bring them up with different ip but with same hostname (DNS updated, eg. On
> kubernetes) Producers will start logging “Broker maybe down”, but will never
> reconnect as the IP address in the log message will keep on referencing the
> old IP.
