Kafka-node: Hangs when creating topic with Kafka 2.0.0 inside docker

[srfrnk]

Complete source code and environment is here
When running with Kakfa 1.1.0 all works.
Changing to Kafka 2.0.0 breaks the code. It hangs while trying to create the topic.
Moreover - changing back to 1.1.0 after that will not fix things and you must restart-docker so that code starts to run.

Likely because BaseProducer is still using the old parameter with "async" boolean.

Workaround is to call the KafkaClient directly to create the topic.

Thanks for the info @hyperlink
Sadly it doesn't help.
I updated the repo with your suggestion. You can make sure it's what you meant.
Any more ideas?

Did you push your changes?

Using the KafkaClient should work these tests are passing.

Pushed the changes just now.
Sorry. You can see the code now.

@srfrnk you need to pass an array of objects with the following fields topic, partitions and replicationFactor see the readme.

Done... + added client.connect just in case....
Now throws:

TypeError: Cannot read property 'host' of undefined

Has this been resolved, I'm running into the same issue.

I'm running into the same issue:

const uuid = require('uuid');

const kafka = require("kafka-node");
const client = new kafka.KafkaClient();

const topic1 = uuid.v4();
const topic1ReplicationFactor = 1;
const topic1Partitions = 5;
const topic2 = uuid.v4();
const topic2ReplicationFactor = 1;
const topic2Partitions = 1;

client.connect();
client.createTopics(
  [
    {
      topic: topic1,
      partitions: topic1Partitions,
      replicationFactor: topic1ReplicationFactor
    },
    {
      topic: topic2,
      partitions: topic2Partitions,
      replicationFactor: topic2ReplicationFactor
    }
  ], (err, data) => console.log(err, data)
);

The error is:

/home/pavlovdog/.........../node_modules/kafka-node/lib/kafkaClient.js:282
    var broker = this.getBroker(controllerMetadata.host, controllerMetadata.port);
                                                   ^

TypeError: Cannot read property 'host' of undefined

Pretty strange, because I've taken this code directly from the test (link). I'm running Kafka with https://github.com/wurstmeister/kafka-docker, just docker-compose up -d, without any extra settings.
