One previously identified issue was that teardown may not be invoked on a DoFn if there is an exception calling setup on a different fused DoFn. However I believe that if the dataflow runner abandons a MapTaskExecutor for some reason not related to an exception in user processing (cache timeout or exception during backend commit) that we may not be invoking the teardown method. This can lead to leaking resources if they are created in setup and require teardown to close them. An example of this is the KafkaProducer in KafkaWriter [here](sdks/java/io/kafka/src/main/java/org/apache/beam/sdk/io/kafka/KafkaWriter.java#L57). -- This is an automated message from the Apache Git Service.
