[jira] [Created] (KAFKA-9018) Kafka Connect - throw clearer
exceptions on serialisation errors
Robin Moffatt created KAFKA-9018:
------------------------------------
Summary: Kafka Connect - throw clearer exceptions on serialisation errors
Key: KAFKA-9018
URL: https://issues.apache.org/jira/browse/KAFKA-9018
Project: Kafka
Issue Type: Improvement
Components: KafkaConnect
Reporter: Robin Moffatt
When Connect fails on a deserialisation error, it doesn't show if that's the *key or value* that's thrown the error, nor does it give the user any indication of the *topic/partition/offset* of the message. Kafka Connect should be improved to return this information.
