Subject [jira] [Created] (YARN-8932) ResourceUtilization cpu is misused in oversubscription
Date Mon, 22 Oct 2018 20:50:00 GMT
Haibo Chen created YARN-8932:
--------------------------------

             Summary: ResourceUtilization cpu is misused in oversubscription
                 Key: YARN-8932
                 URL: https://issues.apache.org/jira/browse/YARN-8932
             Project: Hadoop YARN
          Issue Type: Sub-task
    Affects Versions: YARN-1011
            Reporter: Haibo Chen
            Assignee: Haibo Chen


The ResourceUtilization javadoc mistakenly documents the cpu as a percentage represented by
a float number in [0, 1.0f], however it is used as the # of vcores used in reality.

See javadoc and discussion in YARN-8911.
  /**
   * Get <em>CPU</em> utilization.
   *
   * @return <em>CPU utilization</em> normalized to 1 CPU
   */
  @Public
  @Unstable
  public abstract float getCPU();
