Sorry if that is unclear , it was just showing a full example of using the client, you don't want to call stop till you are done consuming, if ever.
Feel free to send a PR with any clarification you think works
Thanks !

I have downloaded the code and tried the example code mentioned in the readme file, I have no luck in running the sample program. Every time i start the program, it starts and doesn't consume any data from kafka.

Later I realized issue is because of calling
consumer.stop() //returns a Future[Unit] that completes when the connector is stopped. It sends an event FSMConnector and ends up in unhandled section of FSMConnector in Actors.scala whenUnhandled{ case Event(ConnectorFSM.Stop,
) => log.error("Unhandled event and stopping the consumer") connector.shutdown() sender() ! ConnectorFSM.Stop context.children.foreach( ! StreamFSM.Stop) stop() }
I commented consumer.stop() and it started reading data from kafka, I have to figure out how to stop the program once it finished all data from kafka. I have tested it from eclipse and command line, both had same problem. Am i doing something wrong?
Appreciate your help.
