这是SPARK-22685中的交叉发布。
TL; DR - 如果DynamoDB中不存在分片检查点（==完全新鲜），则从Kinesis读取的Spark Streaming应用程序可以正常运行。但是，如果存在检查点（例如，由于应用程序重新启动），则大多数时间都会失败。
该应用使用 Spark Streaming 2.2.0 和 spark-streaming-kinesis-asl_2.11 。 当使用检查点的分片数据（由KCL写入DynamoDB）启动应用程序时，在几次成功批次（数量不同）之后，这就是我在日志中看到的内容：
首先，租约丢失：
17/12/01 05:16:50 INFO LeaseRenewer: Worker 10.0.182.119:9781acd5-6cb3-4a39-a235-46f1254eb885 lost lease with key shardId-000000000515
然后以随机顺序：无法更新检查点 - 实例不保留此分片的租约和 com.amazonaws.SdkClientException：无法执行HTTP请求：目标服务器未能回复关注，分几批关闭整个应用程序：
17/12/01 05:17:10 ERROR ProcessTask: ShardId shardId-000000000394: Caught exception:

现在，解决方法是从DynamoDB中删除所有分片的所有检查点数据，以便应用程序从InitialPositionInStream.LATEST开始。显然，其缺点是根本不使用检查点信息，数据丢失。
我可能错过了一些明显的东西，所以任何帮助都会受到赞赏。
