Jian He commented on YARN-3272:

attached a screens shot to demonstrate how the locality is represented. 
The table indicates  the number of certain type of containers(i.e. node_local, rack_local,
off_switch) satisfied by certain type of resource requests(i.e. node_local, rack_local, off_switch)

> We can surface the container locality info on the web UI. This is useful to debug "why
my applications are progressing slow", especially when locality is bad.
