> The progress of taskAttempt is not correctly showing when the taskAttempt is failed. The value is 100.00, but actually the taskAttempt is failed. And I found the reason is following:
> {code:title=CompletedTaskAttempt.java|borderStyle=solid}
> @Override
>   public Counters getCounters() {
>     return attemptInfo.getCounters();
>   }
>   @Override
>   public TaskAttemptId getID() {
>     return attemptId;
>   }
>   @Override
>   public float getProgress() {
>     return 1.0f;
>   }
> {code}
> When the taskAttempt is completed, the progress will always return 1.0 whenever the result is failed or succeed. This will let users confused. May be it should be reset to 0 better. I attach a screen shot of this case.
