> In logical plan, {{SerializeFromObject}} for an array always use {{GenericArrayData}} as a destination. {{UnsafeArrayData}} could be used for an primitive array. This is a simple approach to solve issues that are addressed by SPARK-16043.
> Here is a motivating example.
> {code}
> sparkContext.parallelize(Seq(Array(1)), 1).toDS.map(e => e).show
> {code}
