>             Project: Hadoop YARN
>          Issue Type: Sub-task
>          Components: timelineserver
>    Affects Versions: YARN-5355
>            Reporter: Li Lu
>            Priority: Minor

> I just discovered that we're still using a boolean flag {{timelineServiceV2}} 
> after we introduced {{timelineServiceVersion}}. This sounds a little bit 
> error-pruning. After the discussion I think we should only use and trust 
> {{timelineServiceVersion}}. {{timelineServiceV2}} is set upon client 
> creation. Instead of creating a v2 client and set this flag, maybe we'd like 
> to do some sanity check and make sure the creation call is consistent with 
> the configuration?
