-------------------------------------
Summary: Producer (and probably consumer) retains IP address of
broker instead of resolving
Key: KAFKA-8057
URL: https://issues.apache.org/jira/browse/KAFKA-8057
Project: Kafka
Issue Type: Bug
Components: producer
Affects Versions: 2.1.1
Reporter: Bolke de Bruin
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.
