Sachin Goel commented on FLINK-1901:
------------------------------------
I didn't think there would be any such issue since the sampling itself uses Map
and Reduce operations. I can check if there are any issues. It certainly gave
really good results, which wouldn't happen if it weren't being executed
repeatedly.

>
> In order to be able to implement Stochastic Gradient Descent and a number of
> other machine learning algorithms we need to have a way to take a random
> sample from a Dataset.
> We need to be able to sample with or without replacement from the Dataset,
> choose the relative size of the sample, and set a seed for reproducibility.
