native query not working with cassandra 3.0.9 and DSClientFactory

[bedinsky]

I'm not able to execute native query using cassandra 3.0.9 (centos7) and DSClientFactory
Query result is empty.

    	String useNativeSql = "SELECT * FROM system_schema.keyspaces ";
     	Query q = em.createNativeQuery(useNativeSql);  
    	List result = q.getResultList();

I'm not using thrift client because schema is not generated correctly
