> When ever limit filter is used to get application report using ApplicationBaseProtocol#getApplications,
the applications retrieved are not the latest. The retrieved applications are random based
on the hashcode. 
> The reason for above problem is RM maintains the apps in MAP where in insertion of application
id is based on the hashcode. So if there are 10 applications from app-1 to app-10 and then
limit is 5, then supposed to expect that applications from app-6 to app-10 should be retrieved.
But now some first 5 apps in the MAP are retrieved. So applications retrieved are random 5!!
> I think limit should retrieve latest applications only.
