Marcelo Valle Avila commented on YARN-882: ------------------------------------------ +1 > Specify per user quota for private/application cache and user log files > ----------------------------------------------------------------------- > > Key: YARN-882 > URL: https://issues.apache.org/jira/browse/YARN-882 > Project: Hadoop YARN > Issue Type: New Feature > Reporter: Omkar Vinit Joshi > Assignee: Omkar Vinit Joshi > > 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. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
