Olivier Blanvillain updated SPARK-22036:
----------------------------------------
Description:
The multiplication of two BigDecimal numbers sometimes returns null. Here is a
minimal reproduction:
{code:java}
object Main extends App {
import org.apache.spark.{SparkConf, SparkContext}
import org.apache.spark.sql.SparkSession
import spark.implicits._
val conf = new
SparkConf().setMaster("local[*]").setAppName("REPL").set("spark.ui.enabled",
"false")
val spark = SparkSession.builder().config(conf).appName("REPL").getOrCreate()
implicit val sqlContext = spark.sqlContext
case class X2(a: BigDecimal, b: BigDecimal)
val ds = sqlContext.createDataset(List(X2(BigDecimal(-0.1267333984375),
BigDecimal(-1000.1))))
val result = ds.select(ds("a") * ds("b")).collect.head
println(result) // [null]
}
{code}
was:
The multiplication of two BigDecimal numbers sometimes returns null. This issue
we discovered while doing property based testing for the frameless project.
