> [~sihuazhou] proposed to not only use the list of preferred locations to decide where
to schedule a task, but to also weigh the list according to how often a location appeared
and then select the location based on the weight. That way, we would obtain better locality
in some cases.
> Example:
> Preferred locations list: {{[location1, location2, location2]}}
> Weighted preferred locations list {{[(location2 , 2), (location1, 1)]}}
