> 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.
