Vinod Kumar Vavilapalli commented on YARN-5532: ----------------------------------------------- Tx for your comments, [~asuresh]. bq. If you do make Resource Localization independent of containers, against who would the resources (mem, iobandwidth, storage etc) be accounted against ? Today we only have ref-counting and no resource-usage accounting, but the principles will be the same. I think {{ResourceLocalizationService}} should completely abstract away the requester and just manage everything via a RequesterID - resource usage per requester, notifying a requester when a resource is successfully localized, fails etc. bq. Will this be a service exposed to any container running in the NM? That would be a use-case and API discussion. Today, the two use-cases we have - YARN-1503 and YARN-4876 / YARN-4726 - don't need any container-> NM interaction. The only interaction is with AMs. If new use-cases come up which need container->NM interaction, we can design as part of implementing those use-cases. > Make ResourceLocalizationService inside NodeManager independent of containers > ----------------------------------------------------------------------------- > > Key: YARN-5532 > URL: https://issues.apache.org/jira/browse/YARN-5532 > Project: Hadoop YARN > Issue Type: New Feature > Reporter: Jian He > Assignee: Jian He > > The goal is to enable NodeManagers to localize resources while container is > running.
