Question

我可以写信给kafka。但是，消费不起作用

kafka = KafkaClient(kafka_host_list)
consumer = SimpleConsumer(kafka,'topic-test-development','topic-test-development')

No handlers could be found for logger "kafka.conn"
Traceback (most recent call last):
  File "/home/ubuntu/workspace/feed-tests/tests/kafka_consumer.py", line 44, in <module>
    consumer = SimpleConsumer(kafka,'topic-test-development','topic-test-development')

注意No handlers could be found for logger "kafka.conn"

为记录器添加代码：

logging.basicConfig(
    format='%(asctime)s.%(msecs)s:%(name)s:%(thread)d:%(levelname)s:%(process)d:%(message)s',
    level=logging.DEBUG
)

运行并输出更多信息：

用于消费的python kafka不起作用
