Ewan Higgs commented on HDFS-13777:
-----------------------------------
While we have patches for this to work in the namenode, the implementation at
the time was expected to land in the then-pending SPS service. As the SPS has
been released this work could be picked apart and possibly moved directly to
the SPS service.
> [PROVIDED Phase 2] Scheduler in the NN for distributing DNA_BACKUP work.

> 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.
