[jira] [Updated] (KAFKA-9018) Kafka Connect - throw clearer
exceptions on serialisation errors
[ https://issues.apache.org/jira/browse/KAFKA-9018?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Mario Molina updated KAFKA-9018:
--------------------------------
Affects Version/s: 2.5.0
2.4.1
> 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
> Affects Versions: 2.5.0, 2.4.1
> Reporter: Robin Moffatt
> Assignee: Mario Molina
> Priority: Minor
>
> 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.
> Example message that user will get (in this case caused by reading non-Avro data with the Avro converter)
> {code:java}
> Caused by: org.apache.kafka.connect.errors.DataException: Failed to deserialize data for topic sample_topic to Avro:
> at io.confluent.connect.avro.AvroConverter.toConnectData(AvroConverter.java:110)

> Caused by: org.apache.kafka.common.errors.SerializationException: Error deserializing Avro message for id -1
