> Right now, the NM would send its own log aggregation status to RM
> periodically to RM. And RM would aggregate the status for each application,
> but it will not generate the final status until a client call(from web ui or
> cli) trigger it. But RM never persists the log aggregation status. So, when
> RM restarts/fails over, the log aggregation status will become “NOT_STARTED”.
> This is confusing, maybe we should change it to “NOT_AVAILABLE” (will create
> a separate ticket for this). Anyway, we need to persist the log aggregation
> status for the future use.
