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.
