Junping Du updated YARN-2045:
-----------------------------
Attachment: YARN-2045-v3.patch
Thanks [~jlowe] for above comments.
In v3 patch:
- Remove related interfaces in NMStateStoreService, we can add it back if we
find it useful in future.
- To handle old version type (String) issue, rename DB_SCHEMA_VERSION_KEY, if
cannot loading data against new key, treat it as new version type 1.0
- Still keep PBImpl there, we can improve/remove it if we found it unuseful in
future.
- Address [~vvasudev]'s comments above.
> Data persisted in NM should be versioned
