             Summary: hadoop-sls can not simulate huge scale of YARN
                 Key: YARN-7672
                 URL: https://issues.apache.org/jira/browse/YARN-7672
             Project: Hadoop YARN
          Issue Type: Improvement
            Reporter: zhangshilong
            Assignee: zhangshilong

Our YARN cluster scale to nearly 10 thousands nodes.
We need to do scheduler pressure test.
we start  2000+ threads to simulate NM and AM. So  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.
