> Some people may want to use checkpoint to get a consistent snapshot of the 
> Dataset / RDD. Warn that this is not the case with lazy checkpoint, because 
> checkpoint is computed only at the end of the first action, and the data used 
> during the first action may be different because of non-determinism and 
> retries.
