[jira] [Created] (HDDS-5804) SCMContainerPlacementCapacity is working incorrectly

Aravindan Vijayan created HDDS-5804:
---------------------------------------

             Summary: SCMContainerPlacementCapacity is working incorrectly
                 Key: HDDS-5804
                 URL: https://issues.apache.org/jira/browse/HDDS-5804
             Project: Apache Ozone
          Issue Type: Bug
          Components: SCM
    Affects Versions: 1.2.0
            Reporter: Aravindan Vijayan
            Assignee: Aravindan Vijayan


In SCMContainerPlacementCapacity#chooseNode, we choose the node with a higher utilization % (scmUsed / capacity). This is used by the replication manager to pick a node to replicate an under-replicated container to. This means that if configured, this policy will pick the more used nodes, thereby creating the opposite effect.
