> Key: YARN-10238
> URL: https://issues.apache.org/jira/browse/YARN-10238
> Project: Hadoop YARN
> Issue Type: Improvement
> Reporter: ygl
> Assignee: zhangshilong
> Priority: Major
>
> 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.
