   Hi @Yikun,
   This change has also been adopted by the Spark operator. See https://github.com/kubeflow/spark-operator/pull/2312
   I am an Openshift user myself and therefore ran into a regression. See:  https://github.com/kubeflow/spark-operator/issues/2644
   
   Have you also tested your commands for the home directory?
   
   I tested the home directory with the following small Java class. I don't know how Spark evaluates this.
   ```
   import javax.swing.filechooser.FileSystemView;
   import java.io.File;
   class Home {
       public static void main(String... args) {
           FileSystemView view = FileSystemView.getFileSystemView();
           File file = view.getHomeDirectory();
           String desktopPath = file.getPath();
           System.out.println(desktopPath);
       }
   }
   ```
   The output of the small program returns the following, which is obviously incorrect.
   ```
   java Home
   -anonymous uid}
   ```
   
   Is there a reason to evaluate the GECOS field later?
