             Summary: Kraft network client doesn't handle certificate rotation
                 Key: KAFKA-20931
                 URL: https://issues.apache.org/jira/browse/KAFKA-20931
             Project: Kafka
          Issue Type: Bug
          Components: core
            Reporter: Christo Lolov


Kafka supports "online" certificate rotations via dynamic configurations for 
key and trust stores. In cases such as NodeToControllerChannelManager the 
channel builder registers itself as a reconfigurable so that it gets updates. 
However, KafkaRaftManager's channel builder does not do this as part of 
creating the network client. In the event of a certificate expiry this leads to 
the need to restart the Kafka process so that the new certificates are picked 
up.
