> To support fault tolerant, we need to track task states and ensure the correct/allowed state transitions.
> Here are the task states:
> TaskNew,
> TaskSubmitting,
> TaskRunning,
> TaskCompeleted,
> TaskWaitingForClose,
> TaskClosedByDriver,
> TaskFailedByEvaluatorFailure,
> TaskFailedByGroupCommunication,
> TaskFailedAppError,
> TaskFailedSystemError
> Here are the events taht trigger the state transition:
> SubmittingTask,
> RunningTask,
> CompleteTask,
> WaitingTaskToClose,
> CloseTask,
> FailTaskAppError,
> FailTaskSystemError,
> FaileTaskEvaluatorError,
> FailTaskCommuError
> The state transition diagram is defined the the Fault Tolerant design doc. It is attached.
