Table 'performance_schema.session_variables' doesn't exist

Question

After upgrading MySQL to 5.7.8-rc and loging to server I got error:

Table 'performance_schema.session_variables' doesn't exist 

I can't find any solution for this. Can you help ?

Answer 1

I was able to log on to the mysql server after running the command @robregonm suggested:

mysql_upgrade -u root -p --force 

A MySQL server restart is required.

Answer 2

The mysql_upgrade worked for me as well:

# mysql_upgrade -u root -p --force # systemctl restart mysqld
