Jorne, I have around hundred big csv files in my local machine. Each file has some number of columns which has sensitive information in it. I don't want to drop the columns manually.
Now I have to bring those files into hive external tables, but I want to make sure that the columns which has sensitive information must be masked. Is there any way of doing it? Thanks for your time!
