> 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.
