             Summary: add localization and container launch time to 
ContainerMetrics at NM to show these timing information for each active 
container.
                 Key: YARN-3363
                 URL: https://issues.apache.org/jira/browse/YARN-3363
             Project: Hadoop YARN
          Issue Type: Improvement
            Reporter: zhihai xu
            Assignee: zhihai xu


add localization and container launch time to ContainerMetrics at NM to show 
these timing information for each active container.
Currently ContainerMetrics has container's actual memory usage(YARN-2984),  
actual CPU usage(YARN-3122), resource  and pid(YARN-3022). It will be better to 
have localization and container launch time in ContainerMetrics for each active 
container.
