@Before
public void setUp() throws Exception {
  initializeTargetTestRoot();
  
  // Make  user and data dirs - we creates links to them in the mount table

  fsTarget.mkdirs(new Path(targetTestRoot,"data"));
  fsTarget.mkdirs(new Path(targetTestRoot,"dir2"));
  fsTarget.mkdirs(new Path(targetTestRoot,"dir3"));
  FileSystemTestHelper.createFile(fsTarget, new Path(targetTestRoot,"aFile"));
  
  
  // Now we use the mount fs to set links to user and dir
  // in the test root
  
  // Set up the defaultMT in the config with our mount point links
