Hi If you could add the library which you are using for your coadings that would be great for us to use and learn. For example which library need to import for converting RDD to dataframe. Since you are using databricks notebook the library might be inbuilt. When we are tying in IDE we are getting error. If i use this code i am getting error for the line toDF. I am googling it but not getting exact answer.

This is working with below code in IDE

val list_data=Seq(("Babu", 20), ("Raja", 8), ("Mani", 75), ("Kalam", 100), ("Zoin", 7), ("Kal", 53))
val df1=spark.createDataFrame(list_data).toDF("Name", "Marks")
df1.show()
