> 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.
