[jira] [Created] (HDDS-8491) Update PipelinePlacementPolicies to use SCMContainerPlacementPolicies

Neil Joshi created HDDS-8491:
--------------------------------

             Summary: Update PipelinePlacementPolicies to use SCMContainerPlacementPolicies
                 Key: HDDS-8491
                 URL: https://issues.apache.org/jira/browse/HDDS-8491
             Project: Apache Ozone
          Issue Type: Bug
            Reporter: Neil Joshi


Currently, there are two sets of implementations for placement policies, pipelinePlacementPolicies and SCMContainerPlacementPolicies.  The SCMContainerPlacementPolices are more up-to-date and complete than the pipelineplacementpolicies.  This Jira is to re-use the SCMContainerPlacementPolicies for pipeline placement.

 

Currently the SCMContainerPlacementRackScatter is used by the PipelinePlacementFactory to implement the rack scatter policy for pipeline placement.  This should be expanded to include,

{{{}SCMContainerPlacementCapacity{}}},
{{{}SCMContainerPlacementRackAware{}}}, {{SCMContainerPlacementRandom}}

As discussed in https://github.com/apache/ozone/pull/4002#discussion_r1039234550.
