How to populate all possible combination values in columns using Spark SQL

[Aakash Basu]

Hi,

I've described the problem in Stack Overflow with a lot of detailing, can
you kindly check and help if possible?

I'd be absolutely fine if someone solves it using Spark SQL APIs rather
than plain spark SQL query.

Thanks,
Aakash.
