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

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.

Before making saveAsTextFile use map(x => x.mkString(",")

rdd.map(x => x.mkString(",").saveAsTextFile(path)

Output will not have bracket.
