Description

Hello,

I am trying to perform a rolling upgrade from 0.10.0.1 to 1.0.0, and according to the instructions in the documentation, I should only have to upgrade the "inter.broker.protocol.version" parameter in the first step. But after setting the value to "0.10.0" or "0.10.0.1" (tried both), the broker refuses to start with the following error:

[2017-11-20 08:28:46,620] FATAL  (kafka.Kafka$)
java.lang.IllegalArgumentException: requirement failed: log.message.format.version 1.0-IV0 cannot be used when inter.broker.protocol.version is set to 0.10.0.1
        at scala.Predef$.require(Predef.scala:224)
        at kafka.server.KafkaConfig.validateValues(KafkaConfig.scala:1205)
        at kafka.server.KafkaConfig.<init>(KafkaConfig.scala:1170)
        at kafka.server.KafkaConfig$.fromProps(KafkaConfig.scala:881)

        at kafka.Kafka$.main(Kafka.scala:82)
        at kafka.Kafka.main(Kafka.scala)

I checked the instructions for rolling upgrades to previous versions (namely 0.11.0.0), and in here it's stated that is also needed to upgrade the "log.message.format.version" parameter in two stages. I have tried that and the upgrade worked. It seems it still applies to version 1.0.0, so I'm not sure if this is wrong documentation, or an actual issue with kafka since it should work as stated in the docs.
