Subject: Need help for RDD/DF transformation.
Hello,
S
Hello,
Suppose, I have two RDD or data frame like addressed below.
RDD/DF 1
1, a
3, a
5, b
RDD/DF 2
[1, 2, 3]
[4, 5]
I need to create a new RDD/DF like below from RDD/DF 1 and 2.
1, a
2, a
3, a
4, b
5, b
Is there an efficient way to do this?
Any help will be great.
Thank you.
