> In StorageGroupProcessor, we order sequence file as this:
> ```
> private TreeSet<TsFileResource> sequenceFileTreeSet = new TreeSet<>(
>       (o1, o2) -> {
>         int rangeCompare = o1.getFile().getParentFile().getName()
>             .compareTo(o2.getFile().getParentFile().getName());
>         return rangeCompare == 0 ? compareFileName(o1.getFile(), o2.getFile()) : rangeCompare;
>       });
> ```
> We use string comparison rather than number comparison. That's will cause "10" is smaller than "9". Which is a bug
