Prasanna Subburaj commented on KAFKA-6490:
------------------------------------------
Yes I also faces this issue. I feel that the connector should throw a warning
and should move on to the next message. But still I would like other
contributors to comment on this.
> JSON SerializationException Stops Connect
> -----------------------------------------
>
> Key: KAFKA-6490
> URL: https://issues.apache.org/jira/browse/KAFKA-6490
> Project: Kafka
> Issue Type: Bug
> Components: KafkaConnect
> Affects Versions: 1.0.0
> Reporter: William R. Speirs
> Priority: Major
>
> If you configure KafkaConnect to parse JSON messages, and you send it a
> non-JSON message, the SerializationException message will bubble up to the
> top, and stop KafkaConnect. While I understand sending non-JSON to a JSON
> serializer is a bad idea, I think that a single malformed message stopping
> all of KafkaConnect is even worse.
> The data exception is thrown here:
> [https://github.com/apache/kafka/blob/trunk/connect/json/src/main/java/org/apache/kafka/connect/json/JsonConverter.java#L305]
>
> From the call here:
> [https://github.com/apache/kafka/blob/trunk/connect/runtime/src/main/java/org/apache/kafka/connect/runtime/WorkerSinkTask.java#L476]
> This bubbles all the way up to the top, and KafkaConnect simply stops with
> the message: {{ERROR WorkerSinkTask\{id=elasticsearch-sink-0} Task threw an
> uncaught and unrecoverable exception
> (org.apache.kafka.connect.runtime.WorkerTask:172)}}
> Thoughts on adding a {{try/catch}} around the {{for}} loop in
> WorkerSinkTask's {{convertMessages}} so messages that don't properly parse
> are logged, but simply ignored? This way KafkaConnect can keep working even
> when it encounters a message it cannot decode?
