Description
"KIP-271 Add NetworkClient redirector" purposes the change to accommodate environments without proper DNS support, when KafkaProducer or KafkaConsumer tries to connect to Kafka brokers that are inside another network.
Currently, Kafka client connection fails with "java.io.IOException: Can't resolve address" after Kafka cluster metadata is updated with internal DNS names of brokers, unreachable by Client. The example of such configuration might be a Java Client calling Kafka Cluster from outside of Kubernetes cluster or AWS network.
The KIP improves NetworkClient to redirect the call to alternative network address and provides developers with additional Configurable interface to specify redirection rules.
