> Hi.
> I am playing with the new version of kafka (0.9.0.0).
> Initially I've created cluster of 3 nodes, and created some topics there. Later I've added one more node and triggered partitions reassignment. It's kind of working, but on the new node in the log file there are strange warnings:
> [2015-11-25 14:06:52,998] WARN [ReplicaFetcherThread-1-152], Error in fetch kafka.server.ReplicaFetcherThread$FetchRequest@3f442c7b. Possible cause: org.apache.kafka.common.protocol.types.SchemaException: Error reading field 'responses': Error reading field 'topic': java.nio.BufferUnderflowException (kafka.server.ReplicaFetcherThread)
> I've found similar log messages in the following ticket: https://issues.apache.org/jira/browse/KAFKA-2756
> But there such messages were related to the replication between different versions (0.8 and 0.9).
