[jira] [Created] (HDFS-8984) Move replication queues related methods in FSNamesystem to BlockManager

Haohui Mai created HDFS-8984:
--------------------------------

             Summary: Move replication queues related methods in FSNamesystem to BlockManager
                 Key: HDFS-8984
                 URL: https://issues.apache.org/jira/browse/HDFS-8984
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: Haohui Mai
            Assignee: Haohui Mai


Currently {{FSNamesystem}} controls whether replication queue should be populated based on whether the NN is in safe mode or whether it is an active NN.

Replication is a concept on the block management layer. It is more natural to place the functionality in the {{BlockManager}} class.

This jira proposes to move the these methods to the {{BlockManager}}.
