>          Issue Type: Improvement
>          Components: Drivers

> Some problems with the current connection handing:
> - host-less URLs are assumed to be localhost, when this is more commonly the result of
a malformed URL (exhibit A: the current JdbcDriverTest connection)
> - there is no standard syntax for user/password in the url; attempting to support this
will result in more malformed URLs.  most (all?) other JDBC drivers force you to use the user/pass
or properties constructors instead.
> - finally, a malformed URL can result in a very confusing InvalidRequestException if
you manage to end up with garbage in the "path" component (which becomes keyspace): we send
USE X to the server and if there are non-alphanumeric characters there we will get back a
cryptic antlr parse failure ("line 1:28 no viable alternative at character 'K'")
