我正在使用python 3.6编写kafka producer，python kafka客户端版本是1.4.4。kafka版本是：2.1.0和1.1.1（尝试了两个版本），但是当我向producer写入消息时，抛出以下错误：

KafkaTimeoutError('Failed to update metadata after 60.0 secs.')

这是我的客户代码：

producer = KafkaProducer(
  bootstrap_servers=['mq-server:9092'],
  api_version = (0,10,2,0) # solve no broker error
)

producer.send("dolphin-test".encode('utf-8'),b"test")

这是我修改的服务器配置：

listeners=PLAINTEXT://10.142.0.2:9092
advertised.listeners=PLAINTEXT://10.142.0.2:9092

当使用脚本生成和使用消息时，它工作得很好！这是客户端跟踪输出：

D:\project\souce\pydolphin-service>D:/Programs/Python/Python37/python.exe d:/project/souce/pydolphin-service/dolphin/producer.py
Traceback (most recent call last):
