I have a vague memory of using Hadoop streaming for some tasks, but I don't think it's the best option for this scenario. I might lean towards Sqoop as well.
I practiced a similar question where we had to choose between Sqoop and Hive, and I think Sqoop was the right answer because it handles imports directly from databases.
