> At present there is no limit on the number of files / size of the files
> localized by single user. Similarly there is no limit on the size of the log
> files created by user via running containers.
> We need to restrict the user for this.
> For LocalizedResources; this has serious concerns in case of secured
> environment where malicious user can start one container and localize
> resources whose total size >= DEFAULT_NM_LOCALIZER_CACHE_TARGET_SIZE_MB.
> Thereafter it will either fail (if no extra space is present on disk) or
> deletion service will keep removing localized files for other
> containers/applications.
> The limit for logs/localized resources should be decided by RM and sent to NM
> via secured containerToken. All these configurations should per container
> instead of per user or per nm.
