Zhijie Shen commented on YARN-2837: ----------------------------------- The findbug warnings seem not to be related and valid. {{System.out}} and {{System.err}} are challenged to be dereferenced and may result in NPE. > 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 > > > 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)
