[jira] [Created] (YARN-10238) CLONE - hadoop-sls can not simulate
huge scale of YARN
ygl created YARN-10238:
--------------------------
Summary: CLONE - hadoop-sls can not simulate huge scale of YARN
Key: YARN-10238
URL: https://issues.apache.org/jira/browse/YARN-10238
Project: Hadoop YARN
Issue Type: Improvement
Reporter: ygl
Assignee: zhangshilong
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.
