      Description

      Scenario:-
      ---------------
      Operation on snapshot dir.

      EC policy
      bin> ./hdfs ec -getPolicy -path /dir/
      RS-3-2-1024k
      bin> ./hdfs ec -getPolicy -path /dir/.snapshot/
      FileNotFoundException: Path not found: /dir/.snapshot

      bin> ./hdfs dfs -ls /dir/.snapshot/
      Found 2 items
      drwxr-xr-x - user group 0 2017-12-05 12:27 /dir/.snapshot/s1
      drwxr-xr-x - user group 0 2017-12-05 12:28 /dir/.snapshot/s2

      Storagepolicies
      bin> ./hdfs storagepolicies -getStoragePolicy -path /dir/.snapshot/
      The storage policy of /dir/.snapshot/ is unspecified
      bin> ./hdfs storagepolicies -getStoragePolicy -path /dir/
      The storage policy of /dir/:
      BlockStoragePolicy

      {COLD:2, storageTypes=[ARCHIVE], creationFallbacks=[], replicationFallbacks=[]}

      Which is the correct behavior ?
