-----------------------------------

             Summary: what testListStatusFile verified not consistent with listStatus declaration in FileSystem
                 Key: HADOOP-15101
                 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


  @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?
