> Current version of StreamingContext.stop() directly kills all the data receivers (NetworkReceiver) without waiting for the data already received to be persisted and processed. Fixing this requires the following.
> 1. Each receiver, when it gets a stop signal from the driver, should stop receiving, and then wait for all the received data to have been persisted and reported to the driver.
> 2. The driver, after stopping all the receivers, should wait for all the received to be processed.
