Subject [jira] Updated: (CASSANDRA-1565) cassandra-cli use consistant flags and improve error messages
Date Tue, 18 Jan 2011 15:06:44 GMT


Christoph Hack updated CASSANDRA-1565:

    Attachment: trunk-1565.txt

Update which makes the cassandra-cli command line options more consistent with other tools
(nodetool). In addition to the previous long option names, shorter ones are provided for common
options and additional error handling (e.g. for additional non-recognized options or arguments)
was added.

> 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.
