> 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.
