Tsuyoshi OZAWA commented on YARN-1139:
--------------------------------------

Thank you for sharing the knowledge, [~ste...@apache.org]! I created patch on 
YARN-1172 based on the design you mentioned - overriding 
serviceInit()/serviceStart()/serviceStop(). I'll also take this approach on 
this JIRA, because of the reason you mentioned(e.g. easy error handling).

>             Project: Hadoop YARN
>          Issue Type: Improvement
>          Components: resourcemanager
>    Affects Versions: 2.1.0-beta

> Some of the RM components - state store, scheduler etc. are not services. 
> Converting them to services goes well with the "Always On" and "Active" 
> service separation proposed on YARN-1098.
> Given that some of them already have start(), stop() methods, it should not 
> be too hard to convert them to services.
> That would also be a cleaner way of addressing YARN-1125.
