            Reporter: Ivan Andika


>From [https://github.com/apache/ozone/pull/5666#discussion_r1410542795]

[~XiChen] suggested:

"Maybe can add a new subclass for {{PipelineChoosePolicy}} (such as 
{{{}NearestPipelineChoosePolicy{}}}) to "sort" the datanode when 
{{{}choosePipeline{}}}? This would get a better results."

This will be a useful choose policy so that the pipeline can be closest to the 
client during block allocation and writing.
