hadoop-3.2.x has included 
[HADOOP-16213|https://github.com/apache/hadoop/commit/e0b3cbd221c1e611660b364a64d1aec52b10bc4e]
 which upgraded guava to 27.0-jre, will spark include the change as a new 
profile e.g. Hadoop-3.2 ?

+1, we met the similar issue when multiplying 3+ BigDecimal, although we have a 
workaound to cast them into a smaller number, it's not easy to tell when it 
will fail especially we have more complicated query.

> 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}
