&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Summary: Sequence File's order isn't right
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Key: IOTDB-524
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; URL: https://issues.apache.org/jira/browse/IOTDB-524
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Project: Apache IoTDB
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Issue Type: Bug
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Reporter: Kaifeng Xue


In StorageGroupProcessor, we order sequence file as this:
```
private TreeSet<TsFileResource&gt; sequenceFileTreeSet = new TreeSet<&gt;(
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (o1, o2) -&gt; {
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; int rangeCompare = o1.getFile().getParentFile().getName()
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; .compareTo(o2.getFile().getParentFile().getName());
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; return rangeCompare == 0 ? compareFileName(o1.getFile(), o2.getFile()) : rangeCompare;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; });
```

We use string comparison rather than number comparison. That's will cause "10" is smaller than "9". Which is a bug
