> YARN-3030 makes the per-node aggregator work as the aux service of a NM. It
> contains the states of the per-app aggregators corresponding to the running
> AM containers on this NM. While NM is restarted in work-preserving mode, this
> information of per-node aggregator needs to be carried on over restarting too.
