Tsuyoshi OZAWA commented on YARN-1139:
--------------------------------------
Thank you for the advice, [~zjshen]. I've checked the AbstractService code, and
I've gotten we need to convert all exceptions into ServiceStateException -
subclass of RuntimeException - as you described. I'll check and update a patch
for YARN-1172 based on your advice.
> [Umbrella] Convert all RM components to Services
> ------------------------------------------------
>
> Key: YARN-1139
> URL: https://issues.apache.org/jira/browse/YARN-1139
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: resourcemanager
> Affects Versions: 2.1.0-beta
> Reporter: Karthik Kambatla
> Assignee: Tsuyoshi OZAWA
>
> 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.
