------------------------------------------
Summary: Check for hostnames in CoreUtils.scala
Key: KAFKA-14103
URL: https://issues.apache.org/jira/browse/KAFKA-14103
Project: Kafka
Issue Type: Improvement
Components: core
Reporter: Matthew de Detrich
In the process of working on [https://github.com/apache/kafka/pull/11478] we
realized that Kafka does not do any hostname validation when parsing listener
configurations. It would be ideal to investigate hostname validation so that we
can eagerly short-circuit on invalid hostnames rather than the current
behaviour (this needs to be verified).
