kafka.errors.NoBrokersAvailable exception when running producer example on Mac

Running single-node Kafka cluster on localhost on Mac (OS X 10.11.6) Getting error on attempt to instantiate producer

>>> from kafka import KafkaProducer
>>> producer = KafkaProducer(bootstrap_servers=['localhost:9092'])

getting error

Kafka is up, and running locally and producer from confluent-kafka-python works without issues. Any suggestions what to look for?

Version 1.3.5 of this library (which is latest on pypy) only lists certain API versions 0.8.0 to 0.10.1. So unless you explicitly specify api_version to be (0, 10, 1) the client library’s attempt to discover the version will cause a NoBrokersAvailable error.

an example from my code:

producer = KafkaProducer(
    bootstrap_servers=URL,
    client_id=CLIENT_ID,
    value_serializer=JsonSerializer.serialize,
    api_version=(0, 10, 1)
)

I meet this problem in centos7, and I fix this by using flowing code

       producer = KafkaProducer(bootstrap_servers='localhost:9092', request_timeout_ms=1000000, api_version_auto_timeout_ms=1000000)

It seems increasing this value api_version_auto_timeout_ms may fix this problem.
