您好我使用Kinesis作为我的数据缓冲区，我在下面收到此错误，表示我的访问密钥无效。我试图谷歌周围，其他发布的答案建议将访问密钥更改为正确的。
但是我的情况有点特别，这个错误在运行时出现，这意味着当我的应用程序启动时访问密钥是正确的，但是在运行一段时间之后，访问密钥突然无效。
我怀疑＆＃34; AmazonCloudWatch＆＃34;和＃34; AmazonDynamoDBv2＆＃34;服务客户端库导致问题？或者我的方式来创建＆＃34; AmazonKinesisClient＆＃34;不正确吗？
我未授权在AWS论坛上发布这两项服务的线程，所以我在此发布。非常感谢你。
用于启动AmazonKinesisClient的Scala代码：
val awsCredentialsProvider = new DefaultAWSCredentialsProviderChain()
val kinesisClient = new AmazonKinesisClient(awsCredentialsProvider)

这是因为凭据轮换，有时您尝试使用刚刚过期的凭据访问kinesis。
亚马逊建议的解决方案是在到期前5分钟刷新凭据。更多细节https://aws.amazon.com/premiumsupport/knowledge-center/security-token-expired/
