> 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.
