Option C is just hilarious. The NameNode maintaining a local file system? That's like asking the CEO to manage the photocopier!

Haha, comparing it to asking the CEO to manage the photocopier is spot on. Option C is definitely the odd one out.

I agree, Option C doesn't make sense at all. It's like asking a cat to bark.

This is a classic HDFS question. The NameNode is the central management component, so it makes sense that it would store the metadata and block mapping, not the file data.

I think A is the correct answer. The NameNode is responsible for storing the file metadata, not the actual file content.

Hmm, D sounds like it's the wrong answer. The NameNode definitely doesn't store the file content, that's the job of the DataNodes.

Option C seems a bit off, I'm pretty sure the NameNode doesn't store the actual file content, just the mapping between blocks and DataNodes.
