akhileshchg opened a new pull request, #13130: URL: https://github.com/apache/kafka/pull/13130
3.4 introduced a change that requires cluster.id to be present in meta.properties if the file is available. This information is not persisted by the brokers in old versions (< 0.10). So on upgrade, the requirement check fails and halts the broker start-up. Fixed the requirement to ensure cluster.id is not required in zk mode on upgrade. -- This is an automated message from the Apache Git Service.
