> Make UnknownTopicOrPartitionException a WARN in broker
> ------------------------------------------------------
>
> Key: KAFKA-627
> URL: https://issues.apache.org/jira/browse/KAFKA-627
> Project: Kafka
> Issue Type: Bug
> Components: core
> Affects Versions: 0.8.0
> Environment: Kafka 0.8, RHEL6, Java 1.6
> Reporter: Chris Riccomini
>
> Currently, when sending messages to a topic that doesn't yet exist, the
> broker spews out these "errors" as it tries to auto-create new topics. I
> spoke with Neha, and she said that this should be a warning, not an error.
> Could you please change it to something less scary, if, in fact, it's not
> scary.
