Jason Gustafson created KAFKA-3977:
--------------------------------------
Summary: 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: 0.10.0.0, 0.9.0.1, 0.9.0.0
Reporter: Jason Gustafson
Assignee: Jason Gustafson
Priority: Critical
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.
