Examples of org.apache.hadoop.mapred.SimulatorTaskTracker$SimulatorTaskInProgress

org.apache.hadoop.mapred.SimulatorTaskTracker
Internal helper class used for storing the current status and other auxilliary information associated with a task attempt assigned to a simulator task tracker. WARNING: This is a completely different inner class than the one with the same name in SimulatorJobTracker.

      long subRandomSeed = RandomSeedGenerator.getSeed(
         "forTaskTracker" + numTaskTrackers, masterRandomSeed);
      jobConf.setLong("mumak.tasktracker.random.seed", subRandomSeed);
      numTaskTrackers++;
      port++;
      SimulatorTaskTracker tt = new SimulatorTaskTracker(jt, jobConf);
      long firstHeartbeat = now + random.nextInt(startDuration);
      queue.addAll(tt.init(firstHeartbeat));
    }
    
    // In startDuration + heartbeat interval of the full cluster time each 
    // TT is started up and told on its 2nd heartbeat to beat at a rate 
    // corresponding to the steady state of the cluster
