netcat is listening for a connection on port 9999. It is echoing what you type to its console to anything that connects to 9999 and reads. That is what Spark streaming does.
If you yourself connect to 9999 and write, nothing happens except that netcat echoes it. This does not cause Spark to somehow get that data. nc is only echoing input from the console.
