> Each task uses session variables from client or configs from tajo-site.xml. The session variables and configs are used in task during query processing.
> If invalid configs or invalid session variables are used for a query, the error will be caused in a runtime instead of query init phase. It's bad situation. Invalid values must be detected at the initialization phase.
>  Because each session variable or config varies in its value type and value range, It would be great if each ConfigKey takes a validator for its value and Tajo uses validators for it.
