Description:
ndbd_redo_log_reader provides no help output, and invoking it with --help produces an error.

How to repeat:
jon@flundra:~/bin/mysql-5.1-telco-6.3/bin> ./ndbd_redo_log_reader --help
Error: open file: No such file or directory

Suggested fix:
Provide help output similar to that provided by other NDB utlities.

      bug#36805 - falcon_index_chill_threshold and falcon_record_chill_threshold have values in MB
      
      falcon_index_chill_threshold and falcon_record_chill_threshold accept a value in megabytes. 
      This is non-standard with respect to the rest of the server options, prevents from setting 
      the variables to lower than 1mb, which prevents testing of the chill/thaw mechanism and 
      prevents the user from using the KB, MB and GB modifiers provided by server.
      
      falcon_index_chill_threshold and falcon_record_chill_threshold are now changed to accept a value 
      in bytes.

      The tests falcon_options and falcon_options2 are also changed to work accordingly.

Documented fix as follows in the NDB 6.3.53, 7.0.41, 7.1.30, 7.2.15, and 7.3.4 changelogs:

        The ndbd_redo_log_reader utility now supports a  --help option.
        Using this option causes the program to print basic usage
        information, and then to exit.

Also noted the addition of the option in the program description in the 5.1/5.5/5.6 versions of the Manual.

Closed.
