fvaleri opened a new pull request, #14484: URL: https://github.com/apache/kafka/pull/14484
In KIP-778 we introduced the "unsafe" downgrade in case one of the metadata versions between target and current have changes, as defined in MetadataVersion. This is a lossy downgrade where each node rebuilds its metadata snapshots, omitting the metadata changes. Currently, this is not supported, as shown by the following command. ```sh $ bin/kafka-features.sh --bootstrap-server :9092 downgrade --metadata 3.4 --unsafe Could not downgrade metadata.version to 8. Invalid metadata.version 8. Unsafe metadata downgrade is not supported in this version. 1 out of 1 operation(s) failed. ``` This change fixes the documentation to reflect the current partial implementation, and improves the error message to avoid confusion between metadata.version and Kafka version. -- This is an automated message from the Apache Git Service.
