             Summary: Add E2E test with Minikube and LocalStack
                 Key: SPARK-57900
                 URL: https://issues.apache.org/jira/browse/SPARK-57900
             Project: Spark
          Issue Type: Sub-task
          Components: Kubernetes, Tests
    Affects Versions: 4.3.0
            Reporter: Kousuke Saruta


This sub-task is part of the umbrella [SPARK-57703|https://issues.apache.org/jira/browse/SPARK-57703] (OIDC Credential Propagation).

h2. Problem

We need to verify the full flow (token ingestion -> STS -> S3A read/write -> credential refresh) in a realistic Kubernetes environment.

h2. Goal

An optional end-to-end test that validates the entire credential propagation pipeline.

h2. Scope

* Behind Maven profile {{-Poidc-e2e}} (skipped by default in CI)
* Projected ServiceAccount token -> {{AwsStsCredentialProvider}} -> LocalStack STS -> S3A read/write
* Token rotation mid-job triggers credential refresh and continued S3 access
* Requires Minikube and LocalStack

h2. Acceptance criteria

* A Spark job on Minikube reads/writes S3 (LocalStack) using OIDC-derived credentials.
* Mid-job token rotation results in successful credential refresh (no S3 access failures).
* Test is skipped when profile is not active.
* Setup instructions are documented.
