### What would you like to be improved?
When shuffle-server encounters disk problems and triggers the mechanism of dropping events, we should mark the app data lost.
After then, we could reject the write/read requests by these apps to make job fast fail.
### How should we improve?
_No response_

Contributor guide
Research direction
Start by tracing the shuffle-server path that handles disk problems and drops events, then identify where application data-loss state and write/read request handling are defined. Determine how dropped events should mark an application and how subsequent requests should be rejected; the work is done when affected applications fail fast while unaffected applications retain current behavior.
