    Description

      Noticed this while debugging issues in another application. We saw an error when trying to do a FileSystem.get using an hftp file system on a secure cluster using a proxy user ugi.

      This is a small snippet used

       FileSystem testFS = ugi.doAs(new PrivilegedExceptionAction<FileSystem>() {
                  @Override
                  public FileSystem run() throws IOException {
                      return FileSystem.get(hadoopConf);
                  }
              });
      

      The same code worked for hdfs and webhdfs but not for hftp when the ugi used was UserGroupInformation.createProxyUser
