User for MYsql?

Hello can we run sqoop commands with mysql root user or should we need to create an alternate user for mysql?
If we use root i think there might be some permission problems while it writes to HDFS path?

What about the certification exam? Does he provide the username and password for sqoop query?

Suggestions Please

Thank you

Typically data is stored in other users and not in root user.
In exam username and password of mysql will be provided along with problem statement.
