Manikandan R commented on YARN-6384:
------------------------------------

Using yarn.nodemanager.resource.percentage-physical-cpu-limit won't solve this?

> When using cgroups on yarn, if yarn.nodemanager.linux-container-executor.cgroups.strict-resource-usage is false, user may get very more cpu time than expected based on the vcores. There should be a upper limit even resource-usage is not strict, just like a percentage which user can get more than promised by vcores. I think it's important in a shared cluster.
