> Project: Hadoop YARN

> Now the compare code is :
> return a1.getApplicationId().getId() - a2.getApplicationId().getId();
> Will be replaced with :
> return a1.getApplicationId().compareTo(a2.getApplicationId());
> This will bring some benefits:
> 1,leave applicationId compare logic to ApplicationId class;
> 2,In future's HA mode,cluster time stamp may change,ApplicationId class
> already takes care of this condition.
