But how do I add a new Column to an existing SuperColumn?

You should really look into the class SuperCfTemplate and class SuperCfUpdater in hector. Once they are initialize, do what is needed (example in your question, add a new cf within this scf), then update the changes using the template. Below are a snippet.

SuperCfTemplate<String, String, String> template = new ThriftSuperCfTemplate<String, String, String>(keyspace, "Super1", stringSerializer, stringSerializer, stringSerializer);
SuperCfUpdater<String, String, String> updater = template.createUpdater("key", "newcf");
updater.setString("subname", "1");
template.update(updater);

  • But, if I just want to add the column definition without a key? – Joeya Jun 18 '12 at 19:39
  • @Joeya without a key, how should that row be identified or where should the row store? Please read this [link](http://wiki.apache.org/cassandra/DataModel#Rows) for more information. – Jasonw Jun 19 '12 at 01:39
