Ben Stopford created KAFKA-2900: ----------------------------------- Summary: Error Consuming From Kafka Key: KAFKA-2900 URL: https://issues.apache.org/jira/browse/KAFKA-2900 Project: Kafka Issue Type: Bug Reporter: 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 -- This message was sent by Atlassian JIRA (v6.3.4#6332)
