Subject [jira] Issue Comment Edited: (CASSANDRA-2008) CLI help incorrect in places
Date Thu, 17 Feb 2011 00:16:24 GMT

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

@jon I was combining this with CASSANDRA-2007 to move the demo keyspace out of cassandra.yaml
and into a cli file. In the user groups we always tell people to use the cli to create a keyspace,
but we don't have an example. My understanding was loading schema defs through JConsole was
no longer the preferred method. I went with yaml as we already have it in the tree, can change
if there is an agreed alternative. 

@jonathan Am using literals in the yaml file so newlines are preserved http://www.yaml.org/spec/1.2/spec.html#id2760844
The yaml looks something like
{{noformat}} 
commands:
  - name: NODE_ADD_KEYSPACE
    help: |
    blah blah

    blah
  - name: NODE_UPDATE_KEYSPACE
{{noformat}}

I'll get the rest of the help sorted and then we can edit it if needed. It will not be a straight
lift from cassandra.yaml, but there is more information in cassandra.yaml and I want to make
most of that available in the cli. My main goal here is to cut out some of the simple support
questions.
