> StatusHttpServer is extending org.apache.hadoop.http.HttpServer.  The only additional
feature in StatusHttpServer is TaskGraphServlet.  StatusHttpServer is used by TaskTracker
and JobTracker.  It turns that only JobTracker uses TaskGraphServlet but not TaskTracker.
> So, we should deprecate StatusHttpServer, let TaskTracker and JobTracker use HttpServer
directly, and add TaskGraphServlet to JobTracker.
