scala - How to remove parentheses around records when saveAsTextFile on RDD[(String, Int)]?

Question

I'm using saveAsTextFile(path) in order to save output as text file in later to import the result to DB. The output looks something like this:

(value1, value2)

How to remove the parentheses?

Answer 1

You can try the following which is very basic:

rdd.map(x => x._1 + "," + x._2).saveAsTextFile(path)

You just map your RDD[(A,B)] to an RDD[String] and save it.
