turboFei commented on issue #25797: [SPARK-29043][Core] Improve the concurrent performance of History Server URL: https://github.com/apache/spark/pull/25797#issuecomment-535836589 > By unblocking the cleanForLogs call, you also unblock the cleaner task which may run after it. I didn't see any changes to that code; it should probably check whether some path is being processed before trying to do things with it. I have checked the code of `cleanLogs`, it will clean up the expired paths in `listing` and clear relative record in `blackList`. In this PR, if a path is contained in `processing`, it would not be added into `listing`. So, should we interrupt the tasks which is processing a path has been expired?
