      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.
