> In Standalone mode, the number of cores in Completed Applications of the 
> Master Web Page will always be zero, if sc.stop() is called.
> But the number will always be right, if sc.stop() is not called.
> The reason maybe: 
> after sc.stop() is called, the function removeExecutor of class 
> ApplicationInfo will be called, thus reduce the variable coresGranted to 
> zero.  The variable coresGranted is used to display the number of Cores on 
> the Web Page.
