> When 1:1 edge is used, it would be helpful to find out whether downstream
> tasks ran on the same location provided in the hints by the runtime.
> One of the recent feature in upstream project (hive) used 1:1 edge. Instead
> of checking the logs, it would be useful to have an analyzer to churn out the
> details.
