nemon lou commented on YARN-606:
--------------------------------

The submitApp() method in QueueMetrcis.java cause negative ,it has this logic:
 public void submitApp(String user, int attemptId) {
    if (attemptId == 1) {
      appsSubmitted.incr();
    } else {
      appsFailed.decr();
    }
   ...
  }

Which is introduced in by MAPREDUCE-3870.

> Queue metrcis "apps Failed" can be negative in some cases(more than one attempt for an
application can cause this).
> It's confusing if we use this metrics directly.
