> Key: TAJO-1114
> URL: https://issues.apache.org/jira/browse/TAJO-1114
> Project: Tajo
> Issue Type: Improvement
> Reporter: Hyunsik Choi
> Assignee: Jihun Kang
> Fix For: 0.9.1
>
>
> 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.
