> 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}}.
