> We will do checkpoint when generating a batch and completing a batch. When
> the processing time of a batch is greater than the batch interval,
> checkpointing for completing an old batch may run after checkpointing of a
> new batch. If this happens, checkpoint of an old batch actually has the
> latest information, but we won't recovery from it. Then we may see some RDD
> checkpoint file missing exception during checkpoint recovery.
