我试图在ubuntu中运行monasca-persister组件，但是与kafka相关的文件出错，我的kafka服务器运行良好。
Process Process-2:

所以，我检查错误的文件，但我无法弄清楚出了什么问题
class KafkaConsumer(object):
def __init__(self, kafka_url,
zookeeper_url, zookeeper_path,
group, topic,
fetch_size=1048576,
repartition_callback=None,
commit_callback=None,
commit_timeout=30):
"""Init
kafka_url - Kafka location
zookeeper_url - Zookeeper location
zookeeper_path - Zookeeper path used for partition
negotiation
group - Kafka consumer group
topic - Kafka topic
repartition_callback - Callback to run when the Kafka consumer

self._kazoo_client = None
self._set_partitioner = None

self._commit_callback = commit_callback
self._commit_timeout = commit_timeout
self._last_commit = 0

答案 0 :(得分：1)
KafkaClient类没有任何位置参数。将配置作为关键字参数传递：
self._kafka = kafka.client.KafkaClient(bootstrap_servers=kafka_url)
请参阅source linked from the documentation以了解接受的配置关键字及其默认值。许多相同的配置选项也记录在KafkaConsumer class。
