Li Lu commented on YARN-2837: ----------------------------- Hi [~zjshen], this version looks good to me (disabling the findbugs warning here looks fine to me). One question is about the version storage: seems like LeveldbTimelineStore also has the same logic on storing/loading versions. Maybe we want to make the "version control" logic a unified interface in future? > Timeline server needs to recover the timeline DT when restarting > ---------------------------------------------------------------- > > Key: YARN-2837 > URL: https://issues.apache.org/jira/browse/YARN-2837 > Project: Hadoop YARN > Issue Type: New Feature > Components: timelineserver > Reporter: Zhijie Shen > Assignee: Zhijie Shen > Priority: Blocker > Fix For: 2.7.0 > > Attachments: YARN-2837.1.patch, YARN-2837.2.patch, YARN-2837.3.patch > > > Timeline server needs to recover the stateful information when restarting as > RM/NM/JHS does now. So far the stateful information only includes the > timeline DT. Without recovery, the timeline DT of the existing YARN apps is > not long valid, and cannot be renewed any more after the timeline server is > restarted. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
