> Support UNIT for TimelineMetric
> -------------------------------

>                 Key: YARN-5751
>                 URL: https://issues.apache.org/jira/browse/YARN-5751
>             Project: Hadoop YARN
>          Issue Type: Sub-task
>          Components: ATSv2
>            Reporter: Rohith Sharma K S
>            Priority: Major
>
> ATSv2 allows users to write its metrics using TimelineMetric. But, there is 
> no field to tell what is the UNIT of published metric. This is very difficult 
> when metrics are read. 
> I propose to add UNIT for TimelineMetric so that once user can use this field 
> to tell what is the unit of published metric.  May be this can be optional 
> for few kind or metrics where unit is not required say CPU. But definitely 
> there should be a way to set units while publishing the entities.
