> KinesisReceiver calls worker.run() which is a blocking call (while loop) as per source
code of kinesis-client library - https://github.com/awslabs/amazon-kinesis-client/blob/v1.2.1/src/main/java/com/amazonaws/services/kinesis/clientlibrary/lib/worker/Worker.java.
> This results in infinite loop while calling sparkStreamingContext.stop(stopSparkContext
= false, stopGracefully = true) perhaps because ReceiverTracker is never able to register
the receiver (it's receiverInfo field is a empty map) causing it to be stuck in infinite loop
while waiting for running flag to be set to false. 
> Also, we should investigate a way to have receiver restart in case of failures.
