Description

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.
