Related to Bug #72678 - See, http://dev.mysql.com/doc/refman/5.6/en/innodb-memcached-installing.html

Quoting from manual - Setting Up Required Tables: To configure the memcached plugin so it can interact with InnoDB tables, run the innodb_memcached_config.sql configuration script to install the necessary tables used behind the scenes:

mysql> source MYSQL_HOME/share/innodb_memcached_config.sql

But the configuration script fails if the "test" database doesn't exists:

ERROR 1049 (42000) at line 86: Unknown database 'test'

This seems to be handled in 5.7.6 (post Bug #72678 fix)

[umshastr@hod03]/export/umesh/mysql-5.7.6: diff share/innodb_memcached_config.sql ../mysql-5.6.24/share/innodb_memcached_config.sql

Suggested fix:
5.6 configuration script should include "CREATE DATABASE IF NOT EXISTS test;" just before the "USE test" statement
