      Description

      The bug can be reproduced as following:

      bash-3.2$ ./bin/hadoop fs -lsr                 
      -rw-r--r--   3 tsz supergroup       1366 2008-10-10 17:52 /user/tsz/a.txt
      -rw-r--r--   3 tsz supergroup       1366 2008-10-10 17:52 /user/tsz/b.txt
      bash-3.2$ ./bin/hadoop fs -chown sze a.txt
      bash-3.2$ ./bin/hadoop fs -lsr
      -rw-r--r--   3 sze supergroup       1366 2008-10-10 17:52 /user/tsz/a.txt
      -rw-r--r--   3 tsz supergroup       1366 2008-10-10 17:52 /user/tsz/b.txt
      

      Then, restart cluster ...

      bash-3.2$ ./bin/hadoop fs -lsr
      -rw-r--r--   3 sze                  1366 2008-10-10 17:52 /user/tsz/a.txt
      -rw-r--r--   3 tsz supergroup       1366 2008-10-10 17:52 /user/tsz/b.txt
      

      The group information for a.txt is missing.
