> Currently, all the documentation refers to the default block placement policy.
> However, over time there have been new policies:
> * BlockPlacementPolicyRackFaultTolerant (HDFS-7891)
> * BlockPlacementPolicyWithNodeGroup (HDFS-3601)
> * BlockPlacementPolicyWithUpgradeDomain (HDFS-9006)
> We should update the documentation to refer to them explaining their
> particularities and probably how to setup each one of them.
