--------------------------------

             Summary: (AM/NM/Container)LivelinessMonitor should use monotonic 
time when calculating period
                 Key: YARN-4403
                 URL: https://issues.apache.org/jira/browse/YARN-4403
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Junping Du
            Assignee: Junping Du
            Priority: Critical


Currently, (AM/NM/Container)LivelinessMonitor use current system time to 
calculate a duration of expire which could be broken by settimeofday. We should 
use Time.monotonicNow() instead.
