Jason Lowe commented on YARN-8703: ---------------------------------- The ResourceLocalizedEvent has a local path, so it looks like we can use that to issue a delete request to the container executor to remove the localized resource the NM is no longer tracking. > Localized resource may leak on disk if container is killed while localizing > --------------------------------------------------------------------------- > > Key: YARN-8703 > URL: https://issues.apache.org/jira/browse/YARN-8703 > Project: Hadoop YARN > Issue Type: Bug > Components: nodemanager > Reporter: Jason Lowe > Priority: Major > > If a container is killed while localizing then it releases all of its > resources. If the resource count goes to zero and it is in the DOWNLOADING > state then the resource bookkeeping is removed in the resource tracker. > Shortly afterwards the localizer could heartbeat in and report the successful > localization of the resource that was just removed. When the > LocalResourcesTrackerImpl receives the LOCALIZED event but does not find the > corresponding LocalResource for the event then it simply logs a "localized > without a location" warning. At that point I think the localized resource > has been leaked on the disk since the NM has removed bookkeeping for the > resource without removing it on disk. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
