Sean Owen resolved SPARK-16206.
-------------------------------
Resolution: Not A Problem
If this is more of a discussion, ask at user@. You can implement whatever you
want to produce folds though, so not clear what this is about.
> Defining our own folds using CrossValidator
> -------------------------------------------
>
> Key: SPARK-16206
> URL: https://issues.apache.org/jira/browse/SPARK-16206
> Project: Spark
> Issue Type: Wish
> Components: ML
> Affects Versions: 1.6.2
> Reporter: Danilo Bustos
> Priority: Trivial
>
> I have been using cross validation process in order to train a Naive Bayes
> Model and I realize that it uses kFold method to get the random sampling data
> in order to create the folds. This method return an Array[(RDD[T], RDD[T])]
> of tuples, which I think are the set of different combination of the folds
> for training and testing.
> My question is whether there is any specific reason because the API does not
> allow you to define your own array of folds. I think would be a good idea if
> this capability is supported, it would help a lot.
