I thought it was just 2 replicas, not 3.

I feel like I read that tasks can access multiple replicas, but I can't remember if they need to pull from all three. This is tricky!

This sounds similar to a practice question I did, and I believe the answer was that tasks can pull from any of the replicas, so maybe it's wrong?

I'm not entirely sure, but I remember something about how MapReduce tasks can access replicas. Could it be that they only need one copy?

I think the backup factor means there are 3 copies of each file, so the statement should be true, right?
