java.lang.Object

org.apache.hadoop.fs.s3a.auth.IAMInstanceCredentialsProvider

org.apache.hadoop.fs.s3a.SharedInstanceCredentialProvider

All Implemented Interfaces:

com.amazonaws.auth.AWSCredentialsProvider, Closeable, AutoCloseable

@InterfaceAudience.Public
 @InterfaceStability.Evolving
public final class SharedInstanceCredentialProvider
extends IAMInstanceCredentialsProvider

This credential provider has jittered between existing and non-existing, but it turns up in documentation enough that it has been restored. It extends IAMInstanceCredentialsProvider to pick up its bindings, which are currently to use the EC2ContainerCredentialsProviderWrapper class for IAM and container authentication.

When it fails to authenticate, it raises a NoAwsCredentialsException which can be recognized by retry handlers as a non-recoverable failure.

It is implicitly public; marked evolving as we can change its semantics.
