Is it better for Spark to select from hive or select from file

Viewed 3516

I was just wondering what people's thoughts were on reading from Hive vs reading from a .csv file or a .txt file or an .ORC file, or a .parquet file. Assuming the underlying Hive table is an external table that has the same file format, would you rather read form a Hive table or from the underlying file itself, and why?
