Jason Lowe updated MAPREDUCE-3862: ---------------------------------- Attachment: MAPREDUCE-3862.patch Patch updated for unit test failures. > Nodemanager can appear to hang on shutdown due to lingering DeletionService > threads > ----------------------------------------------------------------------------------- > > Key: MAPREDUCE-3862 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-3862 > Project: Hadoop Map/Reduce > Issue Type: Bug > Components: mrv2, nodemanager > Affects Versions: 0.23.1 > Reporter: Jason Lowe > Assignee: Jason Lowe > Attachments: MAPREDUCE-3862.patch, MAPREDUCE-3862.patch > > > When a nodemanager attempts to shutdown cleanly, it's possible for it to > appear to hang due to lingering DeletionService threads. This can occur when > yarn.nodemanager.delete.debug-delay-sec is set to a relatively large value > and one or more containers executes on the node shortly before the shutdown. > The DeletionService is never calling > {{setExecuteExistingDelayedTasksAfterShutdownPolicy()}} on the > ScheduledThreadPoolExecutor, and it defaults to waiting for all scheduled > tasks to complete before exiting. -- This message is automatically generated by JIRA.
