Subject Re: Experiences with large hama cluster.

I found, "Thread.sleep(REPORT_INTERVAL)" in a loop :/

----
        for (Map.Entry<TaskAttemptID, TaskInProgress> e : runningTasks
           .entrySet()) {          Thread.sleep(REPORT_INTERVAL);
    TaskInProgress tip = e.getValue();          TaskStatus taskStatus
= tip.getStatus();
          if (taskStatus.getRunState() == TaskStatus.State.RUNNING) {
          taskStatus.setProgress(taskStatus.getSuperstepCount());
            if (!tip.runner.isAlive()) {              if
(taskStatus.getRunState() != TaskStatus.State.FAILED) {
taskStatus.setRunState(TaskStatus.State.SUCCEEDED);
LOG.info("Task '" + taskStatus.getTaskId().toString()
  + "' has completed.");              }
taskStatus.setPhase(TaskStatus.Phase.CLEANUP);            }          }
          taskStatuses.add(taskStatus);        }
        doReport(taskStatuses);        Thread.sleep(REPORT_INTERVAL);
