This fixes two issues: 1. The application directory is cleaned up on application exit, regardless if its a clean exit or one due to failure/being killed. This is accomplished using a shutdown hook. 2. The application only cleans up/unregisters if: - The application succeeds - There are no more retry attempts available This allows applications to automatically retry on failure up to the global retry limit (part of the YARN configuration).
