Subject [jira] Created: (MAPREDUCE-1438) Include one minute load average information in TaskTrackerStatus.ResourceStatus
Date Tue, 02 Feb 2010 09:12:18 GMT
Include one minute load average information in TaskTrackerStatus.ResourceStatus
-------------------------------------------------------------------------------

                 Key: MAPREDUCE-1438
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-1438
             Project: Hadoop Map/Reduce
          Issue Type: Wish
          Components: tasktracker
            Reporter: Jaideep
            Priority: Minor


Load averages are useful indicators of overall system CPU and I/O activity. Including load
average information in ResourceStatus could be useful to schedulers in balancing load across
TaskTrackers. Since JDK 1.6, one minute. load information can be obtained using the OperatingSystemMXBean.getSystemLoadAverage()
method.
