> HIVE-17563 reimplemented metrics using native nio interfaces. It used the
> assumption that{{Files.move()}} is atomic operation. It turns out that by
> default it isn't, unless {{ATOMIC_MOVE}} option is specified. Otherwise the
> destination file is unlinked and then the source file is copied.
> This may cause test failure since the file may be temporarily unavailable.
