After taking another look, I think this problem can prevent by `shuffleFileLostEpoch`? All tasks from the failed reduce stage share the same epoch. So only the first fetch failed task can update the `shuffleFileLostEpoch` and unregister the map output. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
