Because we found the log `can't find HDFS storage for appid`, it means that `appIdToStorages` has removed the cache of this app. Because `removereSources` was called only once, but from the HDFS audit log, it can be seen that the shuffle file was deleted at 18:00:55, but was rewritten at 18:00:57, resulting in the loss of the appId of the cache of `appIdToStorages`, However, the cached appId of `shuffleTaskInfos` is still there and cannot be removed. Therefore, this exception occurs when `removeResources` is scheduled again. Therefore, this PR is mainly used to solve the problem that the path cannot be deleted after the cache of appid by appidtostorages expires. -- This is an automated message from the Apache Git Service.
