ascii is part of spark-sql api and can only be used on DataFrames/Datasets.

Convert your RDD to Dataset using then use the ascii function

import spark.implicits._
val a = sc.parallelize(Array("Santosh","Adithya"))

case class Person(val fullName: String)
val ds = a.map(Person).toDS.selectExpr("ascii(fullName)")
ds.show
