Hi, The CassandraResource doesnt have the correct properties based on the path. Have a look at the properties for a non CassandraResource that does exist.
In particular your value for suffix should be null, but its the full path. It looks like your processing of path is wrong. Perhaps the best way of debugging this is to implement the CassandraResource.toString method to print out all the properties in the same way the JcrResource.toString does. Here is a standard JcrResource for reference. curl http://localhost:8080/content/test/subnode.tidy.json 0 (2013-08-16 06:37:25) TIMER_START{ResourceResolution} 78 (2013-08-16 06:37:25)
