> HADOOP-12161 introduced a new {{FileSystem#getStoragePolicy}} call. The DFS
> implementation of the call requires two RPC calls, the first to fetch the
> storage policy ID and the second to fetch the policy suite to map the policy
> ID to a {{BlockStoragePolicySpi}}.
> Fix the implementation to require a single RPC call.
