python和kafka KeyError：-1

Question

Python kafka不起作用。 有什么原因嗎？ 我的意思是我無法將事件連接到kafka，但出現錯誤？ 是否有適用於0.8的kafka客戶端？ 我的意思是這是一台全新的服務器。 我剛剛啟動了它。
我正在使用https://github.com/mumrah/kafka-python

from kafka.client import KafkaClient
kafka = KafkaClient(kafka_domain, 9092)


Traceback (most recent call last):
  File "/home/ubuntu/workspace/rtbhui-devops/simulations/pixel_druid_simulations.py", line 36, in <module>
    kafka = KafkaClient(kafka_domain, 9092)
  File "/usr/local/lib/python2.7/dist-packages/kafka/client.py", line 38, in __init__
    self.load_metadata_for_topics()  # bootstrap with all metadata
  File "/usr/local/lib/python2.7/dist-packages/kafka/client.py", line 247, in load_metadata_for_topics
    self.topics_to_brokers[topic_part] = brokers[meta.leader]
KeyError: -1

在kafka日志中，我看到以下內容。

這在kafka-python 0.9.0版中已修復。 該錯誤是Kafka Python的內部錯誤，而不是kafka服務器的錯誤，僅涉及處理當前沒有引導符的分區（自動創建主題時，任何新主題都會發生這種情況，但在正常操作下很少見）
