> 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.
