[jira] [Commented] (MAPREDUCE-1233) Incorrect Waiting maps/reduces in Jobtracker metrics

    [ https://issues.apache.org/jira/browse/MAPREDUCE-1233?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13230621#comment-13230621 ] 

Koji Noguchi commented on MAPREDUCE-1233:
-----------------------------------------

This seems to be in 1.X/0.20.2XX already? 

However, I'm not sure how the patch is related to "Waiting" metrics.  This only touches failedMap&failedReduce metrics.

> Waiting Maps/Reduces are incorrect in Jobtracker metrics when a job fails. when a map/reduce fails(during job failure), waiting maps/reduce got incremented and doesn't get decremented even after job cleanup.
