Jian He commented on YARN-1521:
-------------------------------
- getNewApplicationId , getDelegationToken. since each call returns a new
ID/Token, not sure this matches with idempotency.
- For the registers protocols. For example, registerNodeManager : if previous
call succeeds, RM didn't crash, registerNodeManager retry because of some
network problem, the next call comes in, this node is deemed as a reconnected
node instead of a new node. Probably AtMostOnce?
> Mark appropriate protocol methods with the idempotent annotation or
> AtMostOnce annotation
