---------------------------------
Summary: 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
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.
