kafka-python 引发 UnrecognizedBrokerVersion 错误

Question

使用kafka-python包构建 KafkaProducer 时出现此错误：

[ERROR] UnrecognizedBrokerVersion: UnrecognizedBrokerVersion
Traceback (most recent call last):
  File "/var/lang/lib/python3.7/imp.py", line 234, in load_module
    return load_source(name, filename, file)
  File "/var/lang/lib/python3.7/imp.py", line 171, in load_source
    module = _load(spec)

    **self.config)
  File "/var/task/kafka/client_async.py", line 240, in __init__
    self.config['api_version'] = self.check_version(timeout=check_timeout)
  File "/var/task/kafka/client_async.py", line 908, in check_version
    version = conn.check_version(timeout=remaining, strict=strict, topics=list(self.config['bootstrap_topics_filter']))
  File "/var/task/kafka/conn.py", line 1228, in check_version
    raise Errors.UnrecognizedBrokerVersion()

代码如下：

from kafka import KafkaProducer
producer = KafkaProducer(bootstrap_servers=os.environ.get('KAFKA_HOST', 'localhost:9092'))

我正在使用 Python 3.7 和 AWS MSK 集群。

只需添加以下内容security_protocol="SSL"即可解决它KafkaProducer：

from kafka import KafkaProducer
producer = KafkaProducer(security_protocol="SSL", bootstrap_servers=os.environ.get('KAFKA_HOST', 'localhost:9092'))
