Ismael Juma commented on KAFKA-3730:
------------------------------------
The error seems to imply that the broker with
`inter.broker.protocol.version=0.9.0.0` is somehow trying fetch data from a
0.8.2.x replica. Are you sure all brokers have indeed been upgraded?
> Problem when updating from 0.8.2 to 0.9.0
> -----------------------------------------
>
> Key: KAFKA-3730
> URL: https://issues.apache.org/jira/browse/KAFKA-3730
> Project: Kafka
> Issue Type: Bug
> Affects Versions: 0.8.2.1, 0.9.0.0
> Environment: SUSE SLE 10.3 64bit
> Reporter: Clint Hillerman
> Priority: Critical
> Labels: newbie
>
> Hello,
> I'm having trouble upgrading a 3 node kafka cluster from 0.8.2.1 to 0.9.0.0.
> I have followed the steps in the upgrade guide here:
> http://kafka.apache.org/documentation.html
> Also, my zookeepers are on the same box as kafka. Each node is both a
> zookeeper and a broker.
> Here's what I did:
> On each box one at a time I,
> - stopped kafka.
> - replaced the code with the new version. Just removed the old kafka dir and
> untared the new 0.9.0.0 version into it's place. Note: the data dir is in a
> different location and was not deleted.
> - copied the server.properties file from the 0.8.2.1 version to the 0.9.0.0
> config dir.
> - added the "inter.broker.protocol.version=0.8.2.X" line to the
> server.properties in 0.9.0.0's config dir.
> - restarted kafka
> After I completed that process on all 3 broker/zookeeper boxes, I switched
> the version to 0.9.0.0 in the server.properties on one broker and restarted
> kafka.
> This caused an error in my server.log. About one every few seconds:
> [2016-05-18 15:00:27,956] WARN [ReplicaFetcherThread-0-12], Error in fetch
> kafka.server.ReplicaFetcherThread$FetchRequest@45597bba. Possible cause:
> org.apache.kafka.common.protocol.types.SchemaException: Error reading field
> 'responses': Error reading field 'topic': java.nio.BufferUnderflowException
> (kafka.server.ReplicaFetcherThread)
> A few other things I tried:
> Restarting zookeepers. There status was also correct when I ran "server
> mapr-zookeeper" qstatus.
> The same process with 9.1 and got this error instead:
> [2016-05-18 14:07:15,545] WARN [ReplicaFetcherThread-0-12], Error in fetch
> kafka.server.ReplicaFetcherThread$FetchRequest@484ad173. Possible cause:
> org.apache.kafka.common.protocol.types.SchemaException: Error reading field
> 'responses': Error reading array of size 1078124, only 176 bytes available
> (kafka.server.ReplicaFetcherThread)
> Restarting everything at once (all broker and zookeeper processes)
> Please let me know if I should provide more information or if posted this in
> the wrong location. I'm also not sure if this is the right location to post
> bugs like this. If there is a forum or something where this is more
> appropriate please point in that direction.
> Thanks,
