Unable to connect to Cassandra datastore...

Hi,

I am using Cassandra as warehouse datastore and using Pentaho Report Designer for generating reports having Pentaho PDI transformation (.ktr) as a data source.

Now, When am trying to create Ad-hoc reports using Pentaho and am failing to connect to Cassandra datastore.

1. How to create datasource to Cassandra in Pentaho Metadata Editor to create Business model ?
2. Is there any other ways to create Business Model in pentaho having Cassandra as datastore ?

Thanks,
Prem
