-------------------------------------
Summary: Capped cpu usage with cgroup strict-resource-usage based
on a mulitplier
Key: YARN-9509
URL: https://issues.apache.org/jira/browse/YARN-9509
Project: Hadoop YARN
Issue Type: New Feature
Components: nodemanager
Reporter: Nicolas Fraison
Add a multiplier configuration on strict resource usage to authorize container
to use spare cpu up to a limit.
Currently with strict resource usage you can't get more than what you request
which is sometime not good for jobs that doesn't have a constant usage of cpu
(for ex. spark jobs with multiple stages).
But without strict resource usage we have seen some bad behaviour from our
users that don't tune at all their needs and it leads to some containers
requesting 2 vcore but constantly using 20.
The idea here is to still authorize containers to get more cpu than what they
request if some are free but also to avoid too big differencies so SLA on jobs
is not breached if the cluster is full (at least increase of runtime is contain)
