Eric Payne commented on YARN-6846: ---------------------------------- {quote} Agreed. It's harmless to the code execution if it does not return ENOENT, but if it does (e.g.: this code is ported to a POSIX-compliant platform) then this prevents the executor from flagging an error from something being already deleted when trying to do a delete. {quote} Great. Thanks [~jlowe] for the fix and [~ebadger] for the review. +1 I will commit this shortly. > Nodemanager can fail to fully delete application local directories when > applications are killed > ----------------------------------------------------------------------------------------------- > > Key: YARN-6846 > URL: https://issues.apache.org/jira/browse/YARN-6846 > Project: Hadoop YARN > Issue Type: Bug > Components: nodemanager > Affects Versions: 2.8.1 > Reporter: Jason Lowe > Assignee: Jason Lowe > Priority: Critical > Attachments: YARN-6846.001.patch, YARN-6846.002.patch, > YARN-6846.003.patch > > > When an application is killed all of the running containers are killed and > the app waits for the containers to complete before cleaning up. As each > container completes the container directory is deleted via the > DeletionService. After all containers have completed the app completes and > the app directory is deleted. If the app completes quickly enough then the > deletion of the container and app directories can race against each other. > If the container deletion executor deletes a file just before the application > deletion executor then it can cause the application deletion executor to > fail, leaving the remaining entries in the application directory lingering. -- 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
