---------------------------------

It looks good to start with providing a multi-tenant query scheduler by
borrowing the Yarn scheduler.
However, as you know, the Yarn scheduler has some problems such as high
scheduling latency.
Do you have any good idea?
> (Umbrella) Implement Tajo Query Scheduler

> Key: TAJO-540
> URL: https://issues.apache.org/jira/browse/TAJO-540
> Project: Tajo
> Issue Type: New Feature
> Reporter: Hyunsik Choi
>
> Currently, there is no Tajo query scheduler. So, all queries launched
> simultaneously compete cluster resource which is managed by
> TajoResourceManager.
> In this issue, we will investigate, design, and implement a Tajo query
> scheduler. This is an umbrella issue for that. We will create subtasks for
> them.
