Arun Suresh commented on YARN-5532: ----------------------------------- bq. I think ResourceLocalizationService should completely abstract away the requester and just manage everything via a RequesterID - resource usage per requester I agree. But I guess we have to think about how this affects the lifetime of the downloaded Resource now. Earlier, since localization was tied to container lifecycle, when a container completes, we know exactly which resources need to be cleaned up. We would now probably need some form of reference checking / garbage collection. Would be interesting to see how we can plug in YARN-4597 too. I am guessing all we need is to send the container lifecycle trigger to the localizing service. But we can discuss more during implementation. > 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.
