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

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

As first, I suggest to port yarn scheduler into Tajo. It will be easy to add the multi-tenant query scheduler
What do you think about to port the yarn scheduler for initial implementation?

> 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.
