[~afchung90] For the first option, you can use {{Checkpoint}}. But the second option (reconstructing state from evaluators) sounds better. You don't need to carry the information every heartbeat interval. Maybe a driver can request to send the information in the next heartbeat (or right away) after the evaluators contact the driver.

> Currently, when we recover an evaluator, we cannot provide complete information of the evaluator back to the user because we do not persist the information anywhere. There are a few options here to keep the information. The first is to persist the information in the DFS, the second is to add the information in EvaluatorStatusProto.
