In [1]: import kafka

Out[2]: '2.0.1'

In [3]: from kafka import KafkaProducer                                         

In [4]: port = 49163

KafkaTimeoutError: KafkaTimeoutError: Failed to update metadata after 60.0 secs.

Minor-ish, but confusing for a newbie. I'd expect an immediate 'Knock it off, I'm closed' error or something.
