> 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.
