> Project: Hadoop YARN

>
> If the NM is started with timeline service v2 turned off AND aux services
> setting still containing "timeline_collector", NM will fail to start up since
> the PerNodeTimelineCollectorsAuxService#serviceInit is invoked and it throws
> an exception. The exception message is a bit misleading and does not indicate
> where the actual misconfiguration is.
> We should update the exception message so that the right error is conveyed
> and helps the cluster admin/ops to correct the relevant yarn config settings.
