Ming Ma commented on MAPREDUCE-6660:
------------------------------------
Thank you [~djp] and [~liuml07]! Sure let me update the unit test. Regarding
the rename to BYTES_READ_LOCAL_DATACENTER, etc. it seems reasonable as it
covers the common scenario, however it might not be general enough to cover all
sort of topologies. For a large cluster with 4 tiers, /edge router/core
switch/TOR/local machine, BYTES_READ_SECOND_OR_MORE_DEGREE_REMOTE_RACK might
mean BYTES_READ_LOCAL_DATACENTER. What do you think?
