Subject [jira] [Created] (HDFS-8815) DFS getStoragePolicy implementation using single RPC call
Date Thu, 23 Jul 2015 17:21:04 GMT
Arpit Agarwal created HDFS-8815:
-----------------------------------

             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.
