How to remove elements of CSV file using RDD in Scala?

val textRDD = sc.textFile("file:/home/bharathi/bhaskar/sample.tab")

I have values in the sample.tab like this

A   B   C   D
1   2   3   4
5   6   7   8
9   10  11  12

I have to delete the second row and show the output

Answer 1

Assuming your second row is 5 6 7 8 , and you don't have any blank lines between your rows. You can use zipWithIndex to assign index to each row and then filter out the row that you don't want based on the index.

textRDD.zipWithIndex.filter(_._2 != 2).map(_._1).foreach(println)

It will print

A B C D
1 2 3 4
9 10 11 12
