> In functions: HierarchicalAllocatorProcess<RoleSorter,
> FrameworkSorter>::initialize() and HierarchicalAllocatorProcess<RoleSorter,
> FrameworkSorter>::allocate(), it does not need to check the
> roleSorter->count() , because the role * always be added to roleSorter.
> So suggest to remove the following lines from initialize() and allocate()
> functions:
> -if (roleSorter->count() == 0) {
> - LOG(ERROR) << "No roles specified, cannot allocate resources!";
> - return;
> -}
