## Was this PR generated or assisted by AI? YES. AI assistance was used for issue triage, drafting the EN/ZH documentation wording, and preparing this PR description. The content mirrors the existing AWS auth section in `emr-serverless.md` and was checked against the reported `UnrecognizedClientException` failure mode on #16963. ## Purpose of the pull request Fixes #16963 (documentation) Users hitting `The security token included in the request is invalid` / `UnrecognizedClientException` when using Amazon EMR (`ADD_JOB_FLOW_STEPS` / `RUN_JOB_FLOW`) had no guidance in classic `emr.md`. EMR Serverless docs already document Worker `conf/aws.yaml` `aws.emr` credentials; classic EMR docs did not. ## Brief change log - Add AWS Authentication Configuration to EN/ZH `emr.md` - Document IAM Role and Access Key setup under `aws.emr` - Call out the common invalid-token error and link EMR Serverless docs (shared config) ## Verify this pull request This pull request is documentation cleanup without runtime test coverage. - Compared against `emr-serverless.md` AWS auth section for consistency - EN + ZH pages updated together ## Pull Request Notice [Pull Request Notice](https://github.com/apache/dolphinscheduler/blob/dev/docs/docs/en/contribute/join/pull-request.md) -- This is an automated message from the Apache Git Service.
