> Yarn is a widely used cluster management system in Hadoop. We need to support Yarn. Roughly, there may be two approaches to support Yarn. The first approach is running the system as a long-running application in Yarn. In this approach, Tajo runs as a long-running application, and Yarn client launches a Tajo cluster and request the cluster resources to RM. The another approach is let the scheduler of Tajo to directly communicate RM.
> In this issue, we will let Tajo to support the first approach. This is an umbrella issue to track all issues about it.
