--------------------------------------
This may be a good catch. I will try to look into it very soon and try to solve it for 1.4

> Key: SPARK-7788
> URL: https://issues.apache.org/jira/browse/SPARK-7788
> Project: Spark
> Issue Type: Bug
> Components: Streaming
> Affects Versions: 1.3.0, 1.3.1
> Reporter: Aniket Bhatnagar
> Assignee: Tathagata Das
> Priority: Blocker
> Labels: kinesis
>
> 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.
