Wei Chen commented on YARN-7672:
--------------------------------
It is an interesting point. So you mean you will set up like two daemons,
one for RM(acts for resource allocation) and the other for NMs(each thread
represents for a NM ?). I am also working on a large scale cluster
simulation project now. I am interested in your configuration for your
simulation(machine capacity, machine load) and your bottleneck (like if the
performance is bottlenecked by CPU or the lock-contention or the other
resources)???

> Our YARN cluster scale to nearly 10 thousands nodes. We need to do scheduler
> pressure test.
> Using SLS,we start 2000+ threads to simulate NM and AM. But cpu.load very
> high to 100+. I thought that will affect performance evaluation of
> scheduler.
> So I thought to separate the scheduler from the simulator.
> I start a real RM. Then SLS will register nodes to RM,And submit apps to RM
> using RM RPC.
