这是在SPARK-22685中交叉发布的。
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 应用程序可以完美运行。但是，如果检查点存在（例如，由于应用程序重启），它大部分时间都会失败。
该应用程序使用Spark Streaming 2.2.0和spark-streaming-kinesis-asl_2.11。当使用检查点分片数据（由 KCL 写入 DynamoDB）启动应用程序时，在几个成功的批次（数量不同）之后，我可以在日志中看到以下内容：
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 - 实例不持有此分片的租约和com.amazonaws.SdkClientException：无法执行 HTTP 请求：目标服务器未能响应跟随，导致整个应用程序在几个批次：
17/12/01 05:17:10 ERROR ProcessTask: ShardId shardId-000000000394: Caught exception:

目前，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. 显然，这样做的缺点是根本没有使用检查点信息，并且数据丢失了。
我可能错过了一些明显的东西，所以任何帮助将不胜感激。
