Subject [jira] [Updated] (YARN-7672) hadoop-sls can not simulate huge scale of YARN
Date Tue, 19 Dec 2017 06:59:00 GMT

     [ https://issues.apache.org/jira/browse/YARN-7672?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

zhangshilong updated YARN-7672:
-------------------------------
    Description: 
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.
