----------------------------------
Summary: Exceptions thrown from SinkTask::close shadow other
exceptions
Key: KAFKA-9955
URL: https://issues.apache.org/jira/browse/KAFKA-9955
Project: Kafka
Issue Type: Bug
Components: KafkaConnect
Affects Versions: 0.10.0.0
Reporter: Greg Harris
Assignee: Greg Harris
If an exception is thrown from SinkTask::close, the exception will shadow any
other previous exception, because SinkTask::close is called from within a
finally block.
Steps to reproduce:
# Throw an exception from SinkTask::start or SinkTask::put
# Throw an exception from SinkTask::close
Expected behavior:
* All exceptions are visible in separate log messages
* The error from SinkTask::start or SinkTask::put is logged as the exception
that caused the task to stop.
Actual behavior:
* The exception from SinkTask::close is logged as the exception that caused
the task to stop.
* The exceptions from either SinkTask::start or SinkTask::put are swallowed
and don't appear in the logs at all.
