> When a nodemanager shuts down it needs to determine if it is likely to be
> restarted. If a restart is likely then it needs to preserve container
> directories, logs, distributed cache entries, etc. If it is being shutdown
> more permanently (e.g.: like a decommission) then the nodemanager should
> cleanup directories and logs.
