--------------------------------------
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.
