Xianyin Xin commented on HADOOP-12409:
--------------------------------------
[[email protected]], i found there're already a {{Time}} class and a {{Timer}}
class in hadoop.util, and {{Timer}} has offered a method to get the monotonic
time. It seems a little messy on using the Time or Clock in the Hadoop project.
My suggestion is, as the first step, we just "move" the clock from yarn.util to
hadoop.util through the way you proposed, and then consider consolidating or
refactoring both the Time and Clock in the following steps. what do you think?
> Move org.apache.hadoop.yarn.util.Clock and relative implementations to hadoop
> Common
