             Summary: AbstractWorkerSourceTask re-processes records filtered out by SMTs on retriable exceptions
                 Key: KAFKA-15145
                 URL: https://issues.apache.org/jira/browse/KAFKA-15145
             Project: Kafka
          Issue Type: Bug
          Components: KafkaConnect
            Reporter: Yash Mayya
            Assignee: Yash Mayya


If a RetriableException is thrown from an admin client or producer client operation in [AbstractWorkerSourceTask::sendRecords|https://github.com/apache/kafka/blob/5c2492bca71200806ccf776ea31639a90290d43e/connect/runtime/src/main/java/org/apache/kafka/connect/runtime/AbstractWorkerSourceTask.java#L388], the send operation is retried for the remaining records in the batch. There is a minor bug in the logic for computing the remaining records for a batch which causes records that are filtered out by the task's transformation chain to be re-processed. This will also result in the SourceTask::commitRecord method being called twice for the same record, which can cause certain types of source connectors to fail. This bug seems to exist since when SMTs were first introduced in 0.10.2
