Description

In branch-1, maps/reduces_failed metric will be incremented when map/reduce task is failed or killed, otherwise maps/reduces_killed metric won't be incremented then.
I found 'maps_killed' and 'reduces_killed' metrics are never incremented not only in QueueMetrics but also in JobTrackerMetrics.
