当所有代理都关闭时，在consumer.poll（）上引发异常

Question

当前，我有3个代理群集kafka环境。当所有代理在轮询时都关闭时，kafka-python（2.0.1）会发出警告，而不是引发异常。我有以下代码-

while True:
        try:
            raw_messages = consumer.poll(timeout_ms=10000, max_records=5)
        except Exception as e:
            print ("Failed to POll -- {e}")
        for topic_partition, messages in raw_messages.items():
            for msg in messages:
                process(msg)

当代理在轮询期间关闭时是否可以引发异常
