             Summary: Clarify that CapacityVolumeChoosingPolicy uses Power of 
Two Random Choices
                 Key: HDDS-14541
                 URL: https://issues.apache.org/jira/browse/HDDS-14541
             Project: Apache Ozone
          Issue Type: Improvement
            Reporter: Ivan Andika
            Assignee: Ivan Andika


CapacityVolumeChoosingPolicy picks two random volumes and pick the volume with 
the lower utilization. This is exactly the Power of Two Random Choices 
strategy. 
 
We can update the Javadoc with the concrete strategy and the related paper 
(https://dl.acm.org/doi/10.1109/71.963420).
