----
> KafkaConsumer swallows exceptions raised from message deserializers
> -------------------------------------------------------------------
>
> Key: KAFKA-3977
> URL: https://issues.apache.org/jira/browse/KAFKA-3977
> Project: Kafka
> Issue Type: Bug
> Components: consumer
> Affects Versions: 0.9.0.0, 0.9.0.1, 0.10.0.0
> Reporter: Jason Gustafson
> Assignee: Jason Gustafson
> Priority: Blocker
> Fix For: 0.10.0.1
>
>
> Message deserialization is currently done in the FetchResponse handler which
> is executed by NetworkClient. Unfortunately, this means that any exceptions
> raised by the deserializer will be eaten by NetworkClient and not raised to
> users. This will be fixed (if unintentionally) in KAFKA-3888, but we should
> make sure that this is fixed in 0.9.0 and 0.10.0 as well.
