That's a good point, But I still think it's D because Hive adapts to the format of the data.

I'm not sure, but I think it might be B. When the table is dropped, the underlying folder in HDFS is deleted.

I disagree, I believe it's C. The schema is defined based on the FROM clause of a SELECT query.

That makes sense. I think I understand now. Thanks for clarifying, Quentin.

Sure, Hive dynamically defines the schema based on the FROM clause of a SELECT query, not the format of the data.

You know, I actually remember learning about this in class. I'm pretty sure option B is correct. When you drop a Hive-managed table, the underlying data in HDFS is gone for good.

I think I got this! Option D is the way to go. Hive is all about flexibility, and it should be able to figure out the schema based on the data format. That's the whole point of Hive, isn't it?

I think all of you are wrong. The answer is actually D. Hive dynamically defines the schema based on the format of the underlying data.

I'm with Jenelle on this. Option C sounds more logical to me.

Haha, these Hive questions are always so confusing. I'm just going to guess and hope for the best. Any of these options could be true, to be honest.

Wait, isn't option B the correct one? When you drop a Hive-managed table, the underlying folder in HDFS should be deleted, right? I'm pretty sure that's how it works.

Option D sounds about right to me. Hive is all about dynamic schema, so it makes sense that it would define the table schema based on the underlying data format.

I'm not sure about this question. The schema definition seems a bit tricky. I'm leaning towards option D, but I'm not completely confident.
