> This sub-task is part of the umbrella
> [SPARK-57703|https://issues.apache.org/jira/browse/SPARK-57703] (OIDC
> Credential Propagation).
> h2. Problem
> No {{CredentialProvider}} implementation exists to exchange an OIDC token for
> AWS STS temporary credentials.
> h2. Goal
> Implement the S3/STS reference provider that calls
> {{AssumeRoleWithWebIdentity}} and returns S3A-compatible credentials.
> h2. Scope
> * Implement {{CredentialProvider}} in {{connector/credential-aws}}
> * Calls {{sts:AssumeRoleWithWebIdentity}} with {{UserContext.rawToken}} and
> configured role ARN
> * Returns {{ServiceCredential}} with keys: {{fs.s3a.access.key}},
> {{fs.s3a.secret.key}}, {{fs.s3a.session.token}}
> * Configuration: {{spark.security.credentials.aws.roleArn}} (required),
> {{sessionName}}, {{durationSeconds}}, {{region}}, {{stsEndpoint}}
> * Works with any STS-compatible endpoint (AWS, MinIO, Ceph)
> h2. Acceptance criteria
> * Given a valid OIDC token and role ARN, provider returns a
> {{ServiceCredential}} with S3A keys.
> * Configuration for non-AWS STS endpoints (MinIO, Ceph) works correctly.
> * Unit tests with mocked STS client cover success, failure, and configuration
> variations.
