Xianyin Xin created YARN-4177:
---------------------------------
Summary: yarn.util.Clock should not be used to time a duration or
time interval
Key: YARN-4177
URL: https://issues.apache.org/jira/browse/YARN-4177
Project: Hadoop YARN
Issue Type: Bug
Reporter: Xianyin Xin
There're many places uses Clock to time intervals, which is dangerous as
commented by [~ste...@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.
