---------------------------------

             Summary: [PROVIDED Phase 2] Scheduler in the NN for distributing DNA_BACKUP work.
                 Key: HDFS-13777
                 URL: https://issues.apache.org/jira/browse/HDFS-13777
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: Ewan Higgs
            Assignee: Ewan Higgs


When the SyncService is running, it should periodically take snapshots, make a snapshotdiff, and then distribute DNA_BACKUP work to the Datanodes (See HDFS-13421). Upon completion of the work, the NN should update the AliasMap.
