### **3.1 Configure Hadoop**

Navigate to **Services** -> **HDFS** -> **CONFIGS** -> **ADVANCED** as shown below

![hdfs-configs](https://github.com/minio/minio/blob/master/docs/bigdata/images/image2.png?raw=true "hdfs advanced configs")

Navigate to **Custom core-site** to configure MinIO parameters for `_s3a_` connector

![s3a-config](https://github.com/minio/minio/blob/master/docs/bigdata/images/image5.png?raw=true "custom core-site")

    // Test provider creation with various configs
    public void test_providerCreationVariousConfigs() {
        // Test with multiple different configs
        FessConfig[] configs = new FessConfig[5];
        FessTimeResourceProvider[] providers = new FessTimeResourceProvider[5];

        for (int i = 0; i < configs.length; i++) {
            final int value = i * 100;
            configs[i] = new FessConfig.SimpleImpl() {

		// timestamp of last successful refresh
		config.lastRefreshedAt = UTCNow()
		return nil
	default:
		return err
	}

	// Reset drivercache built using current config
	clear(config.drivercache)
	// Remove existing tier configs
	clear(config.Tiers)
	// Copy over the new tier configs
	maps.Copy(config.Tiers, newConfig.Tiers)
	config.lastRefreshedAt = UTCNow()
	return nil
}

### El archivo de configuración

Proveniente del ejemplo anterior, tu archivo `config.py` podría verse como:

{* ../../docs_src/settings/app02/config.py hl[10] *}

Nota que ahora no creamos una instance por defecto `settings = Settings()`.

### El archivo principal de la app

Ahora creamos una dependencia que devuelve un nuevo `config.Settings()`.

{* ../../docs_src/settings/app02_an_py39/main.py hl[6,12:13] *}
