Wei Yan commented on YARN-1518:
-------------------------------
The SLS simulator is to evaluate the scheduler performance in a more "real"
way. The simulator keeps the original RM and only removes the low-level
communication stuff. And also the simulator can adopt various user-defined
workloads, and provide real-time tracking of several system metrics (cluster
resource usage, queue resource usage, # of contianers/jobs, etc.). Users can
easily deploy their own workloads in the simulator, and analyze the scheduler
performance in both online and offline mechanisms.

> Project: Hadoop YARN
> Issue Type: Improvement
> Components: scheduler
> Reporter: Chris Douglas
> Priority: Minor

> YARN-1471 added a workaround for the CapacityScheduler and monitors to work
> with the SLS simulator. This issue explores a cleaner integration, including
> tests to verify continued compatibility.
