Severine Tymon created HAWQ-904:
-----------------------------------

             Summary: CLI help output for hawq config is different depending on which help
option is used
                 Key: HAWQ-904
                 URL: https://issues.apache.org/jira/browse/HAWQ-904
             Project: Apache HAWQ
          Issue Type: Bug
          Components: Command Line Tools
            Reporter: Severine Tymon
            Assignee: Lei Chang


hawq config and hawq config --help output the following:

[gpadmin@centos7-namenode hawq]$ hawq --version
HAWQ version 2.0.1.0 build dev
[gpadmin@centos7-namenode hawq]$ hawq config

usage: hawq config [--options]

The "options" are:
   -c --change         Changes a configuration parameter setting.
   -s --show           Shows the value for a specified configuration parameter.
   -l --list           Lists all configuration parameters.
   -q --quiet          Run in quiet mode.
   -v --verbose        Displays detailed status.
   -r --remove         HAWQ GUC name to be removed.
   --skipvalidation    Skip the system validation checks.
   --ignore-bad-hosts  Skips copying configuration files on host on which SSH fails

See 'hawq --help' for more information on other commands.

[gpadmin@centos7-namenode hawq]$ hawq config --help

usage: hawq config [--options]

The "options" are:
   -c --change         Changes a configuration parameter setting.
   -s --show           Shows the value for a specified configuration parameter.
   -l --list           Lists all configuration parameters.
   -q --quiet          Run in quiet mode.
   -v --verbose        Displays detailed status.
   -r --remove         HAWQ GUC name to be removed.
   --skipvalidation    Skip the system validation checks.
   --ignore-bad-hosts  Skips copying configuration files on host on which SSH fails

See 'hawq --help' for more information on other commands.

**while hawq config -h outputs the following:

[gpadmin@centos7-namenode hawq]$ hawq config -h
Usage: HAWQ config options.

Options:
  -h, --help            show this help message and exit
  -c CHANGE, --change=CHANGE
                        Change HAWQ Property.
  -r REMOVE, --remove=REMOVE
                        Remove HAWQ Property.
  -s SHOW, --show=SHOW  Change HAWQ Property name.
  -l, --list            List all HAWQ Properties.
  --skipvalidation      
  --ignore-bad-hosts    Skips copying configuration files on host on which SSH
                        fails
  -q, --quiet           
  -v PROPERTY_VALUE, --value=PROPERTY_VALUE
                        Set HAWQ Property value.
  -d HAWQ_HOME          HAWQ home directory.

The latter (hawq config -h) seems more up-to-date. In particular, the first output contains
errors (-v should be used to supply the value of a changed parameter, not switch to verbose
mode.) There are some minor issues in the latter output too though. `CHANGE`, `REMOVE`, and
`SHOW` placeholders should be replaced with <hawq_property> or HAWQ_PROPERTY
