Jian He commented on YARN-4403:
-------------------------------
patch looks good to me.
one minor suggestion, do you think we can change the base
AbstractLivelinessMonitor to have a default constructor with MonotonicClock
and callers can use this constructor instead ?
> (AM/NM/Container)LivelinessMonitor should use monotonic time when calculating
> period

> 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.
