-----------------------------------
Assignee: Ben Stopford
> Error Consuming From Kafka
> --------------------------
>
> Key: KAFKA-2900
> URL: https://issues.apache.org/jira/browse/KAFKA-2900
> Project: Kafka
> Issue Type: Bug
> Reporter: Ben Stopford
> Assignee: Ben Stopford
>
> More consumer strangeness from the rolling upgrade test.
> Clients dumps out many instances of:
> {[2015-11-26 16:03:26,369] WARN Unknown error fetching data for
> topic-partition test_topic-0
> (org.apache.kafka.clients.consumer.internals.Fetcher)}
> Corresponding server error is:
> {[2015-11-26 16:03:26,483] ERROR [Replica Manager on Broker 1]: Error
> processing fetch operation on partition [test_topic,2] offset 13529
> (kafka.server.ReplicaManager)}
> It would appear we don't log the cause of this error (i.e. the exception) so
> it's a bit tricky working out what happened. I've submitted a patch to
> improve this (https://issues.apache.org/jira/browse/KAFKA-2899).
> The test fails as the consumer stops consuming from this poing
