--------------------------------------
Summary: 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: 0.9.0.0, 0.8.2.1
Environment: SUSE SLE 10.3 64bit
Reporter: Clint Hillerman
Priority: Critical
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,
