                 Key: MAPREDUCE-2653
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-2653
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
          Components: jobtracker, tasktracker
            Reporter: nandan


I have introduced process monitoring system in hadoop inside tasktracker, which analyses the cpu and memory utilization of each map task and allows me to increase/decrease maximum number of map slots dynamically on each node
