I did see the same error, which disappeared when I used jdbcmysql adapter (database.yaml). maybe you have the same misconfiguration.

getting same thing... trying to test without the jdbc drivers. as noted, it's minor, but definitely an issue. connecting to mysql with socket defined, works in MRI... hitting via console.

This is because it tries to use sockets to communicate, which doesn't always work. You need to make sure there is no socket line in the configuration for the database.

This is a configuration error in the database settings for the app, as noted in my comment above.
