Sharad Agarwal commented on MAPREDUCE-1152:
-------------------------------------------
Currently JobTrackerInstrumentation.failed{Map/Reduce} accounts for killed
map/reduce tasks as well. In other places also like in
JobCounter.NUM_FAILED_MAPS, killed and failed both maps are accounted. So I
propose to remove the JobTrackerInstrumentation.killed{Map/Reduce} API since in
framework we do the metering as part of failed API.
> JobTrackerInstrumentation.killed{Map/Reduce} is never called
