What you get should be that defined in filesystem.md, as taken from what HDFS does

>                 URL: https://issues.apache.org/jira/browse/HADOOP-15101
>             Project: Hadoop Common
>          Issue Type: Bug
>          Components: fs, test
>    Affects Versions: 3.0.0-beta1
>            Reporter: zhoutai.zt
>            Priority: Critical

> {code}
>   @Test
>   public void testListStatusFile() throws Throwable {
>     describe("test the listStatus(path) on a file");
>     Path f = touchf("liststatusfile");
>     verifyStatusArrayMatchesFile(f, getFileSystem().listStatus(f));
>   }
> {code}
> 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.
> {code}
> " 
> 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
> "
> {code}
> Which is the expected? The behave in fs contract test or in FileSystem?
