> 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.
