Review Comment:
   I received it and checked it before launching the PR. The keys they used 
were not necessarily the same.
   
   ```java
   public class S3Properties {
     // An alternative endpoint of the S3 service, This could be used to for 
S3FileIO with any
     // s3-compatible object storage service that has a different endpoint, or 
access a private S3
     // endpoint in a virtual private cloud
     public static final String GRAVITINO_S3_ENDPOINT = "s3-endpoint";
     // The static access key ID used to access S3 data.
     public static final String GRAVITINO_S3_ACCESS_KEY_ID = "s3-access-key-id";
     // The static secret access key used to access S3 data.
     public static final String GRAVITINO_S3_SECRET_ACCESS_KEY = 
"s3-secret-access-key";
     // The region of the S3 service.
     public static final String GRAVITINO_S3_REGION = "s3-region";
   
     private S3Properties() {}
   }
   ```
   
   ```
   public class PaimonS3FileSystemConfig extends Config {
   
     public static final String S3_ENDPOINT = "s3.endpoint";
     public static final String S3_ACCESS_KEY = "s3.access-key";
     public static final String S3_SECRET_KEY = "s3.secret-key";
   }
   ```
