> Improve disk load, when queries run simultaneously
> --------------------------------------------------
>
> Key: TAJO-2112
> URL: https://issues.apache.org/jira/browse/TAJO-2112
> Project: Tajo
> Issue Type: Improvement
> Components: Resource Manager, Scheduler
> Reporter: Jinho Kim
> Assignee: Jinho Kim
> Fix For: 0.12.0
>
>
> Currently, tajo uses {{tajo.worker.resource.disks}} for resource scheduler
> and it effects the read performance of leaf task. but it does not consider to
> run query simultaneously.
> The disk load control should move to worker node instead of scheduler.
