cimpl.KafkaException: KafkaError{code=_INVALID_ARG,val=-186,str="No such configuration property: "bootstrap_servers""}

I am trying to produce AVRO data to Kafka topic through python producer script, I already installed python dependencies avro-python3 and confluent_kafka, however when running this script i got below error:


  File "./kafka_producer_avro.py", line 24, in <module>
    kafka_producer_obj = Producer(kafka_config_obj)
cimpl.KafkaException: KafkaError{code=_INVALID_ARG,val=-186,str="No such configuration property: "bootstrap_servers""}

After investigation i found that I should install (libsasl2-dev and libsasl2-modules) dependencies. (sudo yum install gcc libffi-devel python-devel python-pip python-wheel openssl-devel libsasl2-devel openldap-devel), but i got below Error: Unable to find a match: python-devel python-pip python-wheel libsasl2-devel

Solution

  • Your shown error has nothing to do with OS packages.

    It's bootstrap.servers, not with an underscore. Also, the Kafka module is with hyphen, not underscore.

    You can additionally install fastavro with pip.
