Hello guys
Recently I’m looking a solution for capacity scheduler on WorkerNode. But it is
very difficult and many challenges to me.
Jihoon suggested omega scheduler to me. It very interesting and will be help to
implement our scheduler
http://research.google.com/pubs/pub41684.html
As first, I suggest to borrow yarn scheduler queue into Tajo. It will be easy
to add the multi-tenant query scheduler
What do you think about to borrow the yarn scheduler queue for initial
implementation?

> 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.
