Hi @Kunank_kesar
Could you please check the following things to resolve the above issue:
1. Have you closed the spark session properly. For better practise close the spark session if it is not closed.
2. Have you checked the application code by adding some loggers what driver is doing with out stopping the application.
3. As a last step, go to driver machine and collect the thread dumps and see is there any operation it is doing internally.
