             Summary: [SPS]: Refactor Co-ordinator datanode logic to track the block storage movements
                 Key: HDFS-12570
                 URL: https://issues.apache.org/jira/browse/HDFS-12570
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: datanode, namenode
            Reporter: Rakesh R
            Assignee: Rakesh R


This task is to refactor the C-DN block storage movements. Basically, the idea is to move the scheduling and tracking logic to Namenode rather than at the special C-DN. Please refer the discussion with [~andrew.wang] to understand the [background and the necessity of refactoring|https://issues.apache.org/jira/browse/HDFS-10285?focusedCommentId=16141060&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-16141060].
