Quickstart for Schema Registry 0.3.0 not working?

[Achill Schirilla]

Hi,

I'm new to Schema Registry and tried to install it as described in http://registry-project.readthedocs.io/en/latest/schema-registry.html, on a server running CentOS 6.7

But when I try to run the avro-sample (KafkaAvroSerDesApp.java) with the following command:

> cd $REGISTRY_HOME/examples/schema-registry/avro
> java -jar avro-examples-0.3.0.jar -d data/truck_events.csv -p data/kafka-producer.props -sm -s data/truck_events.avsc

then it fails with the following exception:

23:27:29.630 [main] WARN org.apache.kafka.clients.producer.ProducerConfig - The configuration 'schema.registry.url' was supplied but isn't a known config.
23:27:29.631 [main] WARN org.apache.kafka.clients.producer.ProducerConfig - The configuration 'topic' was supplied but isn't a known config.
