Li Cheng commented on HDDS-1577:
--------------------------------
#PR/1366 considers topology and node heaviness in terms of engagement in
pipelines. May add more factors into datanode selection in pipeline placement.
For now, these two major factors are considered enough.
> Add default pipeline placement policy implementation

> This is a simpler implementation of the PipelinePlacementPolicy that can be
> utilized if no network topology is defined for the cluster. We try to form
> pipelines from existing HEALTHY datanodes randomly, as long as they satisfy
> PipelinePlacementCriteria.
