Hi,
Even even further...using/kafka-python (
https://github.com/mumrah/kafka-python) I get the below error. There is
nothing wrong with my kafka server. I can telnet to 9092 just fine.
Again..hoping for a python client that works with gevent. kafka-python did
nok event make it past the connection.
kafka = KafkaClient(kafka_domain, 9092)
No handlers could be found for logger "kafka"
Traceback (most recent call last):
