Jian He updated YARN-3999: -------------------------- Attachment: (was: YARN-3999.5.patch) > RM hangs on draing events > ------------------------- > > Key: YARN-3999 > URL: https://issues.apache.org/jira/browse/YARN-3999 > Project: Hadoop YARN > Issue Type: Bug > Reporter: Jian He > Assignee: Jian He > Attachments: YARN-3999.1.patch, YARN-3999.2.patch, YARN-3999.2.patch, > YARN-3999.3.patch, YARN-3999.4.patch, YARN-3999.patch, YARN-3999.patch > > > If external systems like ATS, or ZK becomes very slow, draining all the > events take a lot of time. If this time becomes larger than 10 mins, all > applications will expire. Fixes include: > 1. add a timeout and stop the dispatcher even if not all events are drained. > 2. Move ATS service out from RM active service so that RM doesn't need to > wait for ATS to flush the events when transitioning to standby. > 3. Stop client-facing services (ClientRMService etc.) first so that clients > get fast notification that RM is stopping/transitioning. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
