> Use java.time.Clock instead of org.apache.hadoop.util.Clock
> -----------------------------------------------------------
>
> Key: HADOOP-19525
> URL: https://issues.apache.org/jira/browse/HADOOP-19525
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: hadoop-common, mapreduce, yarn
> Reporter: Yaniv Kunda
> Assignee: Yaniv Kunda
> Priority: Major
> Labels: pull-request-available
>
> Hadoop's {{Clock}} interface was recently moved from
> {{org.apache.hadoop.yarn.util}} (in hadoop-yarn) to
> {{org.apache.hadoop.util}} (in hadoop-common) as part of YARN-11765.
> I propose to seize the opportunity of this being targeted done for 3.5.0 to
> modernize it usage:
> # Deprecate {{org.apache.hadoop.util.Clock}}
> # Replace all of its usages with {{java.time.Clock}}
> # Replace existing usages of its simple implementations, e.g.
> {{SystemClock}}/{{UTCClock}} with standard {{java.time.Clock}} subclasses,
> e.g. {{Clock.systemUTC()}}
> # Re-implement other implementations, e.g.
> {{MonotonicClock}}/{{ControllerClock}}, as {{java.time.Clock}} subclasses.
> The standard {{java.time.Clock}} has a richer API supports modern
> {{java.time}} classes such as {{Instant}} and {{ZoneId}}, and migration would
> be straightforward:
> Just changing {{org.apache.hadoop.util.Clock.getTime()}} to
> {{java.time.Clock.millis()}}
