amazon-dynamodb - DynamoDb 到 S3 的数据管道转储一直失败

Question

我使用指令为 DynamoDb 设置转储:http://docs.aws.amazon.com/datapipeline/latest/DeveloperGuide/dp-importexport-ddb-part2.html

数据管道设置很好。但是执行任务后我一直有同样的错误。我研究了这个错误，但找不到对我有帮助的东西/提示。是否有人有同样的错误或任何想法为什么可能以及如何解决？错误代码:

Answer 1

找到答案。由于未知原因，EMR 不想写入我在 S3 上的特定存储桶。但是当我创建新的一个桶时 - 转储已成功创建。

因此，如果您以后遇到同样的错误，只需尝试使用另一个 S3 存储桶即可。
