Problem
You are using the dump files from MySQL (earlier version than 5.7 – that has -skip-definer option in mysqlpump), that outputs the DEFINER keyword in Functions and Views, which causes en error when trying to import in a different database that the users do not exist.
Solution
Use the following in your database dump to remove these keywords:
For FUNCTIONS
sed -i 's/DEFINER=\S*\sFUNCTION/FUNCTION/' mysql_dump
For VIEWS
sed -i '/50013\sDEFINER/d' mysql_dump
