> In the current implementation of the
> {{OpportunisticContainerAllocatorAMService}}, we synchronously perform the
> allocation of opportunistic containers. This results in "blocking" the
> service at the RM when scheduling the opportunistic containers.
> The {{OpportunisticContainerAllocator}} should instead asynchronously run as
> a separate thread.
