@burness that is no problem. I have taken a look at the current
implementation of the `RDD`'s `takeSample`; it is very similar to your
implementation. I do still think that implementation has problems, and I am not
sure we should add to the `Dataset`/`Dataframe` API.
You can always use the datasets 's RDD use its `takeSample` method, i.e.:
`spark.createDataset(dataset.rdd.takeSample(...))`.
