Subject [jira] [Created] (MAPREDUCE-4058) adjustable task priority
Date Fri, 23 Mar 2012 01:08:22 GMT
adjustable task priority
------------------------

                 Key: MAPREDUCE-4058
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4058
             Project: Hadoop Map/Reduce
          Issue Type: New Feature
          Components: task-controller
    Affects Versions: 1.0.0
            Reporter: Allen Wittenauer


For those of us that completely destroy our CPUs, it is beneficial to be able to run user
tasks at a different priority than the tasktracker. This would allow for TTs (and by extension,
DNs) to get more CPU clock cycles so that things like heartbeats don't disappear.
