I am having an issue using UDF in Spark (Scala).
我在 Spark (Scala) 中使用 UDF 时遇到问题。 This is a sample code:这是一个示例代码：
import org.apache.spark.sql.{SparkSession, DataFrame}
import org.apache.spark.sql.functions.{col, udf}
val spark = SparkSession.builder.appName("test")
.master("local[*]")
.getOrCreate()
import spark.implicits._
def func(a: Array[Int]): Array[Int] = a
val funcUDF = udf((a: Array[Int]) => func(a))
var data = Seq(Array(1, 2, 3), Array(3, 4, 5), Array(6, 2, 4)).toDF("items")
data = data.withColumn("a", funcUDF(col("items")))
data.show()
The error I get is related to a ClassCastException, saying that it is impossible to cast from scala.collection.mutable.WrappedArray$ofRef to org.apache.spark.sql.catalyst.expressions.ScalaUDF.$anonfun$f$2 .我得到的错误与 ClassCastException 相关，说不可能从scala.collection.mutable.WrappedArray$ofRef为org.apache.spark.sql.catalyst.expressions.ScalaUDF.$anonfun$f$2 。 I add a part of the stack below.我在下面添加了堆栈的一部分。 If it can help, I am using https://community.cloud.databricks.com/ .如果有帮助，我正在使用https://community.cloud.databricks.com/ 。
