zhaostu4 opened a new pull request, #2625: URL: https://github.com/apache/celeborn/pull/2625
### What changes were proposed in this pull request? Prevent invalid Filegroups from being used, eventually throwing FetchFailedException ### Why are the changes needed? #2219 introduced a new feature regarding Filegroups. For multiple tasks belonging to the same shuffleKey, only one of them will actively fetch, and the others will use the cached results in memory. If the Task that actively fetches the Filegroups is killed for some reason (such as another attempt succeeded), it will cause other tasks to obtain invalid Filegroups, eventually leading to stage retry.  ### Does this PR introduce _any_ user-facing change? NO ### How was this patch tested? Internal test. -- This is an automated message from the Apache Git Service.
