Subject [jira] [Commented] (MAPREDUCE-1238) mapred metrics shows negative count of waiting maps and reduces

Koji Noguchi commented on MAPREDUCE-1238:
-----------------------------------------

bq. Is this a duplicate of MAPREDUCE-1233?

Arun, not sure. I think MAPREDUCE-1233 is already in the version we run and we are still seeing
negative metrics for waiting maps/reduces.
