Hi Lewis, In the exception log, I see MockDataStore, rather than HBaseStore, and this might indicate that the configuration cannot be found, or is not showing the correct data store. Could you please check whether gora.properties is setup to show the actual HBaseStore, and this is included in the classpath. Did you check out the source code from scratch?
