------------------------------------
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);
}
...
}
{code}
