> Chaos monkey test in a cluster environment can permanently bring down our
> FlinkKafkaProducer011.
> Typically, after a small number of randomly killed TMs, the data generator
> job is no longer able to recover from a checkpoint because of the following
> problem:
> org.apache.kafka.common.errors.ProducerFencedException: Producer attempted an
> operation with an old epoch. Either there is a newer producer with the same
> transactionalId, or the producer's transaction has been expired by the broker.
> The problem is reproduceable and happened for me in every run after the chaos
> monkey killed a couple of TMs.
