Thanks for your clarifying and consideration, Andrew. Yes renaming the getters should work.

> Filing based on discussion in HDFS-8095. A user might specify a policy that is not appropriate
for the cluster, e.g. a RS (10,4) policy when the cluster only has 10 nodes. The NN should
only allow the client to choose from a pre-approved list determined by the cluster administrator.
