----------------------------------------
Summary: Release Candidate Version 2.3.1-rc1 breaks backward
compatibility in PATCH version
Key: KAFKA-8998
URL: https://issues.apache.org/jira/browse/KAFKA-8998
Project: Kafka
Issue Type: Bug
Components: clients
Affects Versions: 2.3.1
Reporter: Juan Pablo Correa
The expected type for the `preparedResponse` method in the `MetadataResponse`
([https://github.com/apache/kafka/blob/2.3.1-rc1/clients/src/main/java/org/apache/kafka/common/requests/MetadataResponse.java#L466])
has changed from a `List<Node>` to a `Collection<Node>` from the version 2.3.0
to 2.3.1, this breaks the backward compatibility that one would expect from a
PATCH version.
