Zhijie Shen updated YARN-2837:
------------------------------
Attachment: YARN-2837.5.patch
Do two more things in the new patch:
1. Correct the logic of storing version by differentiating the cases of create
a new state store and the existing state store. It seems that
LeveldbTimelineStore needs to be fixed too. Let's treat it as a separate issue.
2. Like RMDelegationTokenIdentifierData, create a
TimelineDelegationTokenIndentifierData to wrap all fields to be serialized into
leveldb for better compatibility if we add more fields in the future.

> 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.
