> Session variables should override query configs in TajoConf.
> ------------------------------------------------------------
>
> Key: TAJO-928
> URL: https://issues.apache.org/jira/browse/TAJO-928
> Project: Tajo
> Issue Type: Improvement
> Components: distributed query plan, planner/optimizer
> Reporter: Hyunsik Choi
> Assignee: Hyunsik Choi
> Fix For: 0.9.0
>
>
> Currently, we should use tajo-site in order to change the configurations
> related queries, such as optimization option or some parameters. It is never
> practical because we need to restart a Tajo cluster in order to change the
> config.
> The main purpose of this issue is to refactor the system of session variable
> and some part to recognize query configs to accept the session variables.
> Also, when there are duplicated configs in session and TajoConf, session
> variables should override the existing config of TajoConf.
