- Login as user **‘spark’**.
- When the job runs, the library can now use **MinIO** during intermediate processing.
- Navigate to a node with the Spark client and access the spark2-client directory:

```
cd /usr/hdp/current/spark2-client
su spark
```

- Run the Apache Spark Pi job in yarn-client mode, using code from **org.apache.spark**:

```
./bin/spark-submit --class org.apache.spark.examples.SparkPi \

{* ../../docs_src/security/tutorial006_an_py39.py hl[4,8,12] *}

When you try to open the URL for the first time (or click the "Execute" button in the docs) the browser will ask you for your username and password:

## Check the username { #check-the-username }

Here's a more complete example.

Use a dependency to check if the username and password are correct.

Si vous ouvrez la documentation automatique de l'API, votre extension apparaîtra au bas du *chemin* spécifique.

<img src="/img/tutorial/path-operation-advanced-configuration/image01.png">

Et dans le fichier openapi généré (`/openapi.json`), vous verrez également votre extension dans le cadre du *chemin* spécifique :

```JSON hl_lines="22"
{

{* ../../docs_src/path_operation_advanced_configuration/tutorial005.py hl[6] *}

Wenn Sie die automatische API-Dokumentation öffnen, wird Ihre Erweiterung am Ende der spezifischen *Pfadoperation* angezeigt.

<img src="/img/tutorial/path-operation-advanced-configuration/image01.png">

Und wenn Sie die resultierende OpenAPI sehen (unter `/openapi.json` in Ihrer API), sehen Sie Ihre Erweiterung auch als Teil der spezifischen *Pfadoperation*:

```Python
images: list[Image]
```

:

{* ../../docs_src/body_nested_models/tutorial008.py hl[15] *}

Die interaktive API-Dokumentation wird entsprechend aktualisiert und erlaubt jetzt mehrere Werte.

<img src="/img/tutorial/query-params-str-validations/image02.png">

### Query-Parameter-Liste / Mehrere Werte mit Defaults

Und Sie können auch eine Default-`list`e von Werten definieren, wenn keine übergeben werden:

// string to a slice of bytes.) The source and destination may overlap. Copy
// returns the number of elements copied, which will be the minimum of
// len(src) and len(dst).
func copy(dst, src []Type) int

// The delete built-in function deletes the element with the specified key
// (m[key]) from the map. If m is nil or there is no such element, delete
// is a no-op.

///

La documentación interactiva de API se actualizará en consecuencia, para permitir múltiples valores:
