@linwen @stanlyxiang @radarwave - Thank you for the comments and
suggestions.
@radarwave - Please see the comments inline
1. I think we should keep the legacy command to do reload in case it's hard
coded in some user cases, print a deprecated message should be fine.
> The change that is committed prints a message as seen below and exits. I
can change the message and let the command continue.
```
hawq stop cluster -u
To reload GUC values without restarting hawq cluster use 'hawq
reload-config <object>'
```
2. Make sure all the related help messages and documents are updated.
> This is something that will go into incubator-hawq-docs and am working on
scoping the change for this.
3. Chose a proper name for this option before user start to use it,
'reload' or 'reload-config' or something else?
> reload sounds good. Also, am open for any other suggestions
4. Add test for this option.
> Sure, let me see how we plug test into the codebase. Any pointers are
appreciated.
