Description

Reproduce steps:
1. Create a empty file on Swift via Swift client(e.g Cyberduck)
2. Use Hadoop Swift API to get file status. The following is the code example:

        Configuration hadoopConf = new Configuration();
        hadoopConf.addResource("swift-site.xml"); // Set Swift configurations

        FileSystem fs = FileSystem.get(new URI("swift://bdd-edp.bddcs/"), hadoopConf);
        FileStatus[] statuses = fs.listStatus(new Path("/mydir"));
        for(FileStatus status : statuses) {
            System.out.println(status);
        }

Result:

SwiftFileStatus{ path=swift://bdd-edp.bddcs/mydir/emptyfile; isDirectory=true; length=0; blocksize=33554432; modification_time=1476875293230}

API treated empty file as a directory. That is incorrect.
