-----------------------------------
Summary: DFS getStoragePolicy implementation using single RPC call
Key: HDFS-8815
URL: https://issues.apache.org/jira/browse/HDFS-8815
Project: Hadoop HDFS
Issue Type: Bug
Components: hdfs-client
Affects Versions: 2.8.0
Reporter: Arpit Agarwal
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.
