Error 'too many values to unpack' in KafkaAdminClient: _send_request_to_controller

Dear kafka-python team,

We start using the API KafkaAdminClient (1.4.4) to create a Topic on a kafka version 1.1 (0.11.0 protocol). We use the following code: kac_dst = KafkaAdminClient(bootstrap_servers=bootstrap_servers,client_id='data') logger.info("Creating topic {}".format(topic_name)) topic_list = [] topic = NewTopic(name=topic_name, num_partitions=2, replication_factor=3) topic_list.append(topic) response = kac_dst.create_topics(new_topics=topic_list, validate_only=True)

The following error occur while executing create_topics function:

kafka/admin/client.py", line 398, in create_topics return self._send_request_to_controller(request) kafka/admin/client.py", line 335, in _send_request_to_controller for topic, error_code in getattr(response, "topic_errors", response.topic_error_codes): ValueError: too many values to unpack (expected 2)

If we set validate_only=False, using one element or few,the same error occur, but the topic/s are created .

Regards, Pablo.

Using kafka-python 1.4.6 didn’t work for me though, I’m surprised this fix didn’t make it into the release.

This fix was released in 1.4.5, so it should be available in 1.4.6… additionally, the only commit to https://github.com/dpkp/kafka-python/commits/master/kafka/admin/client.py since 1.4.6 was released would not affect this.

Are you positive you tested this correctly? You should start with a fresh virtualenv to doublecheck…

Confirming that installing from master works, thanks for the tip! For anyone interested: pip install git+git://github.com/dpkp/kafka-python.git

EDIT: Made a mistake while testing, it does work when using 1.4.6 😃
