> IIUC it is possible for users to create a generic TimelineEntity and set an arbitrary entity type. For example, for a YARN app, the right entity API is ApplicationEntity. However, today nothing stops users from instantiating a base TimelineEntity class and set the application type on it. This presents a problem in handling these YARN system entities in the storage layer for example.
> We need to ensure that the API allows only the right type of the class to be created for a given entity type.
