      Description

      HDFS-6435 adds static user group name id mapping. The mapping is a one to one mapping.

      What makes this feature easy to use is to support squash and range based mapping as that in traditional NFS configuration (e.g., http://manpages.ubuntu.com/manpages/hardy/man5/exports.5.html)

      # Mapping for client foobar:
      #    remote     local
      uid  0-99       -       # squash these
      uid  100-500    1000    # map 100-500 to 1000-1500
      gid  0-49       -       # squash these
      gid  50-100     700     # map 50-100 to 700-750
