    Description

      There're many places uses Clock to time intervals, which is dangerous as commented by stevel@apache.org in HADOOP-12409. Instead, we should use hadoop.util.Timer#monotonicNow() to get monotonic time. Or we could provide a MonotonicClock in yarn.util considering the consistency of code.
