[jira] Commented: (MAPREDUCE-1152) JobTrackerInstrumentation.killed{Map/Reduce} is never called

    [ https://issues.apache.org/jira/browse/MAPREDUCE-1152?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12769603#action_12769603 ] 

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.
