Arun C Murthy updated MAPREDUCE-220:
------------------------------------
Status: Open (was: Patch Available)
TaskStatus isn't really a 'public' api (MAPREDUCE-1623 & HADOOP-5073).
Thus TaskStatus.ResourceStatus shouldn't be exposed directly to the end-user.
We probably should convert the fields in ResourceStatus into Counters and use
that as the primary interface for the end-user, also we should store them into
JobHistory etc.
