> When I use the command,I see the command help description,but the help 
> description doesn't make it clear,especially the argument 'port',It's easy to 
> mistake for port (default 9866) in 'dfs.datanode.address'.Therefore, in order 
> to use this command better,I add some descriptions about the arguments.
