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.
