If I see anyone suggest HTML or XML, I'm walking out of this exam. This is a no-brainer - Avro is the only choice that makes sense here. Unless, of course, you're into data compression that's about as effective as using a sponge to bail out a sinking ship.

Hey, don't knock CSV! It may be simple, but sometimes simple is best. Although, I guess if you're dealing with a ton of images, Avro might be the way to go. Gotta keep that file size down, am I right?

I think CSV would be a good option for storing the data in HDFS as it is widely supported and easy to work with.

Hold up, are we really considering HTML or XML for this? What is this, the 90s? Let's keep it modern and efficient, folks. Avro or bust!

I'm partial to JSON myself. It's human-readable, integrates well with Python, and is a pretty standard format for web-based data. But I can see the benefits of Avro too.
