HadoopDynamicTemporaryAWSCredentialsProvider (Flink : FileSystems : S3 FS Hadoop 1.18.1-cp10 API)

java.lang.Object
- org.apache.flink.fs.s3.common.token.HadoopDynamicTemporaryAWSCredentialsProvider

All Implemented Interfaces:

software.amazon.awssdk.auth.credentials.AwsCredentialsProvider, software.amazon.awssdk.identity.spi.IdentityProvider<software.amazon.awssdk.identity.spi.AwsCredentialsIdentity>
```
@Internal
public class HadoopDynamicTemporaryAWSCredentialsProvider
extends Object
implements software.amazon.awssdk.auth.credentials.AwsCredentialsProvider
```
Support dynamic session credentials for authenticating with AWS using SDK v2. Please note that users may reference this class name from configuration property fs.s3a.aws.credentials.provider. Therefore, changing the class name would be a backward-incompatible change.
This credential provider must not fail during construction, because that would break the chain of credential providers it is registered in. It is, however, expected to fail fast from resolveCredentials() by throwing NoAwsCredentialsException when no delegation token credentials are available yet; the surrounding AwsCredentialsProviderChain treats that as a signal to move on to the next provider in the chain.
