#PROBLEM

`mysql.innodb_table_stats` is part of the MySQL 5.6 install. mysql_upgrade does not generate them. Why ?

- When you install MySQL 5.6 from scratch, that file is generated.
- The file `innodb_table_stats.ibd` does not exists in the mysql schema in MySQL 5.5
- MySQL 5.5's mysql_upgrade is not aware of any innodb system tables.
- In fact, there are five(5) `.ibd` files in MySQL 5.6 in the mysql schema.

#SOLUTION

Please look at these posts I wrote last year on how to make them
