The problem is that Schema Registry's service address seems to be hardcoded or wrongly detected. It must be not localhost:8081, but registry:8081. There is no ability to specify this address to avro console producer.

@vlad1777d Check your schema register process is healthy?

OneCricketeer commented 5 years ago

This seems to be a typo... registry:8081 should not be in the broker-list option.

The hard-coded http://localhost:8081 comes from kafka-avro-console-producer, and is because you forgot to include a --property schema.registry.url parameter
