> Tens of thousands of meaningless logs are frequently printed during
> ResourceManager startup and recover container.
> As we know, ResourceManager will always keep 10k application information by
> default. In our very big scale cluster, it is very usual that resourcemanager
> try to recover the containers which already finished and does not exist in
> ResourceManager but still reported by nodemanager.
> Under this case, below logs will be frequently printed, more importantly,
> this log is meaningless, in real production setups, the maintainers actually
> more care about which containers are properly recovered or killed not the
> ones are skipped.
> The related code are as follows,
> !screenshot-1.png!
> So we move the log into function killOrphanContainerOnNode().
> !screenshot-2.png!
> Only the containers to be killed need to be loged which is vital for trouble
> shooting to distinguish whether the containers are kill by hadoop inner
> mechanism or by users themselves.
