Raghu Angadi commented on HADOOP-2381:
--------------------------------------

That implies {{getOwner()}} won't be overrriden right? It would be some thing 
like:{code}
String FsPermission.getOwner() {
     if (owner == null) {
        loadOwner();
    } 
    return owner;
}

protected void setOwner(String owner) {
  this.owner = owner;
}
protected void loadOwner() {
  if (owner != null) {
    owner = "";
  }
}

// and  sub class overrides loadOwner()

String FsPermissionSubClass.loadOwner {
   // do this class specific stuff.
   setOwner(newOwner);
}
{code}
