Consuming messages from azure event hubs #273

Open cubbuk opened 3 years ago

cubbuk commented 3 years ago

I am following the azure event hub documentation for consuming messages from a topic.

I have created a kafkacat.conf file similar to following

metadata.broker.list=<enter event hubs namespace>.servicebus.windows.net:9093
security.protocol=SASL_SSL
sasl.mechanisms=PLAIN
sasl.username=$ConnectionString
sasl.password=<enter event hubs connection string>
socket.timeout.ms=30000
api.version.request=false
metadata.request.timeout.ms=30000

But I fail to receive any messages with the following command:

 kafkacat -C -b <enter event hubs namespace>.servicebus.windows.net:9093 -t my-topic -o beginning -d broker

Some issues I see in the following error output are the following lines:

Broker changed state CONNECT -> APIVERSION_QUERY

Any idea what am I missing here?

Thanks for any input

You probably shouldn't set api.version.request to false, that's only needed for Apache Kafka <0.10 brokers (really old), so remove that config setting.

Also make sure to use the latest librdkafka and kafkacat, and if the problem persists reproduce with -d broker,security,protocol.

I get this same error with nothing obvious with -d broker,metadata,protocol,security

OP are you also trying to access behind a proxy?

Currently our proxy only exposes traffic via AMQp, and rejects other protocols.

I suspect this is the issue as Event Hubs may require AMQp in order to connect.
