> {color:#0000ff}Hive::listFilesCreatedByQuery{color} does an exists(), an
> isDir() and then a listing call. This can be expensive in object stores. We
> should instead directly list the files in the directory (we'd have to handle
> an exception if the directory does not exists, but issuing a single call to
> the object store would most likely still end up being more performant).
