cassandra-cli use consistant flags and improve error messages
-------------------------------------------------------------
Key: CASSANDRA-1565
URL: https://issues.apache.org/jira/browse/CASSANDRA-1565
Project: Cassandra
Issue Type: Improvement
Components: Tools
Affects Versions: 0.7 beta 1
Environment: Centos 5 using
http://mirror.lividpenguin.com/pub/apache//cassandra/0.7.0/apache-cassandra-0.7.0-beta1-bin.tar.gz
Reporter: Ian Rogers
Priority: Minor
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.
