Hi all, Consider the following case:
import java.sql.Timestamp case class MyProduct(t: Timestamp, a: Float) val rdd = sc.parallelize(List(MyProduct(new Timestamp(0), 10))).toDF() rdd.printSchema() The output is: root |-- t: timestamp (nullable = true) |-- a: float (nullable = false) How can I set the timestamp column to be NOT nullable?
