Subject [jira] [Created] (MAPREDUCE-3528) The task timeout check interval should be configurable independent of mapreduce.task.timeout

The task timeout check interval should be configurable independent of mapreduce.task.timeout
--------------------------------------------------------------------------------------------

                 Key: MAPREDUCE-3528
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-3528
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: mr-am, mrv2
    Affects Versions: 0.23.0
            Reporter: Siddharth Seth


TaskHeartbeatHandler sleeps for 'mapreduce.task.timeout' - between each check. If a task/NM
goes bad immediately after starting a task - the timeout is detected in ~2x the configured
timeout interval.
