Christoph Hack commented on CASSANDRA-1565:
-------------------------------------------

Yeah, now the output is just like I had in mind and your custom addOption() is a little bit
cleaner than the OptionBuilder stuff before. I like it, good work! :)

> nodetool uses "-h" to specify the host to connect to but cassandra-cli uses "-host" which
is a pain to remember.
> More importantly, if you do use "-h" then there's no error!  If you do this and then
try to "show keyspaces" or some such you just get an entirely accurate though confusing "not
connected to a cluster" error.
> 1. Make the flags consistant amongst all the tools where appropriate.
> 2. If you supply a flag to a tool it doesn't recognise then the tool should error immediately
and display its usage message.
