             Summary: Job.monitorAndPrintJob function can sleep most for 596 hours when jobclient.progress.monitor.poll.interval is misconfigured , causing the job to hang  
                 Key: MAPREDUCE-7328
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-7328
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: client
    Affects Versions: 3.3.0
            Reporter: Tina Shan


The loop terminates depending on a configurable value and there is little sanity checking on this value. When jobclient.progress.monitor.poll.interval is misconfigured to INT_MAX, it can cause the loop to sleep at most for 596 hours. The thread would get stuck and never report progress to the user even if the job moves forward. We suggest adding a cap value or a warning message.
  
{code:java}
 public boolean monitorAndPrintJob() 
      throws IOException, InterruptedException {
    ...
    while (!isComplete() || !reportedAfterCompletion) {
      if (isComplete()) {
        reportedAfterCompletion = true;
      } else {
        Thread.sleep(progMonitorPollIntervalMillis);
      }
    ...
}
