-Why this would cause problems? Line 1026 is mainly for concurrency control to prevent a file being deleted concurrently multiple times.-

I see! If a file is created but never opened, then it won't be deleted...

> In [BufferCache.java#L817|https://github.com/apache/asterixdb/blob/adfb63361a1808aadb1782aee03acc4d9af8eb0c/hyracks-fullstack/hyracks/hyracks-storage-common/src/main/java/org/apache/hyracks/storage/common/buffercache/BufferCache.java#L817], we create the file and register it. However, it does not belong to a FileHandle.
> In [BufferCache.java#L1026|https://github.com/apache/asterixdb/blob/adfb63361a1808aadb1782aee03acc4d9af8eb0c/hyracks-fullstack/hyracks/hyracks-storage-common/src/main/java/org/apache/hyracks/storage/common/buffercache/BufferCache.java#L1026], the BufferCache will not unregister the file as it's not in the fileInfoMap.
> This probably the reason for the sporadic _the file is already mapped_ issue?
