HTML? Really? I thought this was a data storage question, not a web design exam. Let's stick to the actual file formats, shall we?

CSV is a classic choice, but it might not be the best for complex data structures. I'd say Avro or JSON are better options here.

I'd go with JSON. It's human-readable, easy to parse, and widely supported by data tools.

Avro, definitely! It's a compact, efficient, and schema-based format that works great with MapReduce and Python.

I agree with Leonor, Avro is a good choice for storing data in HDFS and processing it with MapReduce.

I think we should use Avro because it supports schema evolution and is efficient for MapReduce processing.
