how to convert to rdd before storing. I want to do some transformations

i am attaching the whole code

val input = sc.textFile("dbfs:/FileStore/shared_uploads/Recent9/customerorders.csv")

val mappedInput = input.map(x=>(x.split(",")(0), x.split(",")(2).toFloat))

val totalByCustomer = mappedInput.reduceByKey(_+_)

val premiumCustomers = totalByCustomer.filter(x => x._2 > 5000)

val doubledAmount = premiumCustomers.map(x=>(x._1, x._2*2)).persist(StorageLevel.MEMORY_ONLY)
