--------------------------------------
Thank you, [~lolee_k],
{code}
212 if (strictResourceUsageMode) {
213 limits = getOverallLimits(containerCPU);
214 } else {
215 limits = getOverallLimits(containerCPU *
maxResourceUsagePercentInNonstrictMode);
213 } 216 }
{code}
As I mentioned above, this is not backward compatible.
{code}
212 if (strictResourceUsageMode) {
215 limits = getOverallLimits(containerCPU *
maxResourceUsagePercentInStrictMode);
214 }
{code}
> Add configuratin to set max cpu usage when strict-resource-usage is false

> 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.
