> *schedulePendingTasks* on the LlapTaskScheduler currently goes through all
> the pending tasks and tries to allocate them based on their Priority -- if a
> priority can not be scheduled completely, we bail out as lower priorities
> would not be able to get allocations either.
> An optimization here could be to only walk through the nodes with capacity
> (if any) ,and not all available hosts, for scheduling these tasks based on
> their priority and locality preferences.
