----------------------------------
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.
