> For fault tolerant, IMRU tasks, MapTaskHost and UpdateTaskHost should implement IObserver<ICloseEvent>. When they receive ICloseEvent, it will verify if the closing event is send from driver based on the message in the event, then trow IMRUTaskException with a define message to inform the driver it is closed.
> The change should be backward compatible. If the the IMRU tasks are not bound to the task configuration, the event won't be received.
