Connector module is executed by the kafka connector framework. For debugging, we can use the standalone mode. we can configure IDE to use the ConnectStandalone main function as entry point.

2. connector properties file need specify the connector class name "connector.class" for debugging

3. worker properties file can copied from kafka folder /usr/local/etc/kafka/connect-standalone.properties
