https://github.com/apache/spark/pull/15813
Any thoughts on modifying `JsonToStruct` to support arrays (and options),
then parsing could be something like:
```
dataset.select(
Column(Inline(
JsonToValue(
ArrayType(schema),
options,
Column("value").expr))))
```
Likely out of scope for this pull request, but if there is a push to
migrate from `RDD[T]` to `Dataset[T]` it would clean things up a bit.
