[HADOOP-15101] what testListStatusFile verified not consistent with listStatus declaration in FileSystem

Description

  @Test
  public void testListStatusFile() throws Throwable {
    describe("test the listStatus(path) on a file");
    Path f = touchf("liststatusfile");
    verifyStatusArrayMatchesFile(f, getFileSystem().listStatus(f));
  }

In this case, first create a file f, then listStatus on f，expect listStatus returns an array of one FileStatus. But this is not consistent with the declarations in FileSystem, i.e.

" 
List the statuses of the files/directories in the given path if the path is a directory.
Parameters:
f given path
Returns:
the statuses of the files/directories in the given patch
"

Which is the expected? The behave in fs contract test or in FileSystem?
