    Description

      Around line 691:

              FSDataInputStream fis = clientCache.getDfsInputStream(userName,
                  Nfs3Utils.getFileIdPath(handle));
      
              try {
                readCount = fis.read(offset, readbuffer, 0, count);
      

      fis may be null, leading to NullPointerException
