On a big dataset explicitly unpersist train and validation folds allows to load more data into memory in the next loop iteration. On my environment (single node 8Gb worker RAM, 2 GB dataset file, 3 folds for cross validation), saved more than 5 minutes.

There was a problem hiding this comment.
Seems reasonable to me, except that moving the cache() call here doesn't do anything. It won't be materialized until it's accessed anyway. So this reduces to making sure to properly unpersist the RDDs.
