---------------------------------------------

Hi Hongchao,

You haven't really answered my questions, so I'll try to clarify:
I may be wrong but point 1 should be a few lines of code at most.
I don't understand why Point 2 is something we'd want to do.
Point 3 in the description deserves a separate JIRA and discussion - it seems 
unrelated to client ports.

Finally, a patch of this size that includes logic changes and refactoring would 
be very difficult to review.

> I attach a new one which contains check for when dynamic config file is set 
> server list shouldn't exist in static 
> config.

There was already a check, what case did it miss ? :

           } else if ((key.startsWith("server.") || key.startsWith("group") || 
key.startsWith("weight")) && zkProp.containsKey("dynamicConfigFile")) {
                throw new ConfigException("parameter: " + key + " must be in a 
separate dynamic config file");
            } 

> Keep the client port upon parsing config

> 1. Current implementation ignored and removed "clientPort" on parsing. For 
> the sake of backward compatibility, "clientPort" should be kept and used upon 
> parsing config on fresh boot.
> 2. When getting clientPort from both the old config and dynamic file, the one 
> in dynamic file is of higher priority.
> 3. When "dynamicConfigFile" is set in zoo.cfg and not empty, standalone mode 
> will be disabled.
