Per discussion offline, store the latest sequence number separately to avoid potential race condition of reusing the sequence number. 2. Fix the version related code according to YARN-2952. 3. Fix the potential findbugs warnings that may be introduced by prior patch. > 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, YARN-2837.4.patch, YARN-2837.5.patch, YARN-2837.6.patch, YARN-2837.7.patch > > > Timeline server needs to recover the stateful information when restarting as RM/NM/JHS does now.
