[logs.txt](https://github.com/user-attachments/files/28796295/logs.txt) @Aggarwal-Raghav Could you please try executing the same steps with my latest changes and confirm? I have fixed the Tez UI-related ATS fields according to the new behavior in Hadoop 3.5.0. With these changes, I am able to submit a DAG and view its status in the Tez UI. I have attached the screenshots above for reference. Thank you ! cc: @abstractdog -- This is an automated message from the Apache Git Service.
