------------------------------

             Summary: log.message.format.version should default to inter.broker.protocol.version
                 Key: KAFKA-3827
                 URL: https://issues.apache.org/jira/browse/KAFKA-3827
             Project: Kafka
          Issue Type: Improvement
    Affects Versions: 0.10.0.0
            Reporter: Jun Rao


Currently, if one sets inter.broker.protocol.version to 0.9.0 and restarts the broker, one will get the following exception since log.message.format.version defaults to 0.10.0. It will be more intuitive if log.message.format.version defaults to the value of inter.broker.protocol.version.

java.lang.IllegalArgumentException: requirement failed: log.message.format.version 0.10.0-IV1 cannot be used when inter.broker.protocol.version is set to 0.9.0.1
