> KafkaIO reader might stop reading from Kafka without any explicit error
> message if KafkaConsumer throws a runtime exception while polling for
> messages. One of the Dataflow customers encountered this issue (see [user@
> thread|https://lists.apache.org/thread.html/c0cf8f45f567a0623592e2d8340f5288e3e774b59bca985aec410a81@%3Cuser.beam.apache.org%3E])]
> 'consumerPollThread()' in KafkaIO deliberately avoided catching runtime
> exceptions. It shoud handle it.. stuff happens at runtime.
> It should result in 'IOException' from start()/advance(). The runners will
> handle properly reporting and closing the readers.
