Mukul Kumar Singh created HDFS-11968:

             Summary: ViewFS: StoragePolicies commands fail with HDFS federation
                 Key: HDFS-11968
                 URL: https://issues.apache.org/jira/browse/HDFS-11968
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: hdfs
            Reporter: Mukul Kumar Singh
            Assignee: Mukul Kumar Singh

hdfs storagepolicies command fails with HDFS federation.

For storage policies commands, a given user path should be resolved to a HDFS path and
storage policy command should be applied onto the resolved HDFS path.

  static DistributedFileSystem getDFS(Configuration conf)
      throws IOException {
    FileSystem fs = FileSystem.get(conf);
    if (!(fs instanceof DistributedFileSystem)) {
      throw new IllegalArgumentException("FileSystem " + fs.getUri() +
          " is not an HDFS file system");
    return (DistributedFileSystem)fs;
