## **3. Configure Hadoop, Spark, Hive to use MinIO**

After successful installation navigate to the Ambari UI `http://<ambari-server>:8080/` and login using the default credentials: [**_username: admin, password: admin_**]

### **3.1 Configure Hadoop**

 *
 * Warning: Do not use this if there is a chance that you might have multiple connections (even plain
 * HttpURLConnections, for the complete JRE) to the same host with different or mixed anonymous/authenticated
 * credentials. Authenticated connections can/will be reused.
 *
 * @deprecated This is broken by design, even a possible vulnerability. Deprecation is conditional on whether future JDK
 *             versions will allow to do this safely.

	Endpoint  string
	AccessKey string

	if e.Bucket != "" {
		return fmt.Sprintf("Remote service endpoint offline, target bucket: %s or remote service credentials: %s invalid \n\t%s", e.Bucket, e.AccessKey, e.Err.Error())
	}
	return fmt.Sprintf("Remote service endpoint %s not available\n\t%s", e.Endpoint, e.Err.Error())
}

3. Check crawler logs: `logs/fess-crawler.log`
4. Manually trigger re-indexing:
   - Admin > Scheduler
   - Run "Default Crawler" job

#### Issue: Authentication errors on API calls

**Solution**:
- Verify credentials: default is `admin`/`admin`
- Check if API is enabled in `system.properties`
- Use proper authentication header:
  ```bash
  curl -u admin:admin ...
  # or
  curl -H "Authorization: Basic YWRtaW46YWRtaW4=" ...

     * @param securityAuthentication The security authentication.
     * @param providerUrl The provider URL.
     * @param principal The principal.
     * @param credntials The credentials.
     * @return The environment for LDAP connection.
