> We need to define the history data classes have the exact fields to be
> stored. Therefore, all the implementations don't need to have the duplicate
> logic to exact the required information from RMApp, RMAppAttempt and
> RMContainer.
> We use protobuf to define these classes, such that they can be ser/des
> to/from bytes, which are easier for persistence.
