Append a column to Data Frame in Apache Spark 1.3

Question

Is it possible and what would be the most efficient neat method to add a column to Data Frame?

More specifically, column may serve as Row IDs for the existing Data

Answer 1

not sure if it works in spark 1.3 but in spark 1.5 I use withColumn:

import sqlContext.implicits._
import org.apache.spark.sql.functions._


df.withColumn("newName",lit("newValue"))

I use this when I need to use a value that is not related to existing columns of the dataframe

This is similar to @NehaM's answer but simpler
