Hi all,
I have a RDD with *MANY *columns (e.g., *hundreds*), how do I add one more
column at the end of this RDD?
For example, if my RDD is like below:
123, 523, 534, ..., 893
536, 98, 1623, ..., 98472
537, 89, 83640, ..., 9265
7297, 98364, 9, ..., 735
......
29, 94, 956, ..., 758
how can I efficiently add a column to it, whose value is the sum of the 2nd
and the 200th columns?
Thank you very much.
