> In YARN-3030, to start the per-app aggregator only for a started AM
> container, we need to determine if the container is an AM container or not
> from the context in NM (we can do it on RM). This information is missing,
> such that we worked around to considered the container with ID "xxxx_01" as
> the AM container. Unfortunately, this is neither necessary or sufficient
> condition. We need to have a way to determine if a container is an AM
> container on NM. We can add flag to the container object or create an API to
> do the judgement. Perhaps the distributed AM information may also be useful
> to YARN-2877.
