neils-dev opened a new pull request, #4002: URL: https://github.com/apache/ozone/pull/4002
## What changes were proposed in this pull request? Add new pipeline provider pipeline placement policy, `PipelinePlacementPolicy` that prioritizes container fault tolerance ensuring whenever possible each pipeline is on a separate rack. This new container placement policy is devised for fault tolerance similar to the idea of HDFS-7891, `BlockPlacementPolicyRackFaultTolerant`. The implementation reuses the existing `replication manager` container policy, `SCMContainerPlacementRackScatter `for closed containers, adapting it for use with the open container `RatisPipelineProvider` for pipeline placement on separate racks whenever possible. ## What is the link to the Apache JIRA https://issues.apache.org/jira/browse/HDDS-7265 Please replace this section with the link to the Apache JIRA) ## How was this patch tested?
