> In the beginning of a shuffle map stage, driver needs to select external 
> shuffle services as the mergers of the shuffle partitions for the 
> corresponding shuffle.
> We currently leverage the immediate available information about current and 
> past executor location information for this selection purpose. Ideally, this 
> would be behind a pluggable interface so that we can potentially leverage 
> information tracked outside of a Spark application for better load balancing 
> or for a disaggregate deployment environment.
