Actually, why do we need to do this step? The original code seems to do the
right thing:
```
class FileSystem ...
public static FileSystem get(Configuration conf) throws IOException {
return get(getDefaultUri(conf), conf);
}
public static URI getDefaultUri(Configuration conf) {
return URI.create(fixName(conf.get(FS_DEFAULT_NAME_KEY, DEFAULT_FS)));
}
```
That is, the original code gets the file system using the URI stored in the
config. Standard practice is that the caller must have set the file system
property: that is how we tell a "file:///" system from an HDFS system, etc.
So, isn't the problem here with the caller?
