Example test code which passes:

multiget_slice test code

  public void testMultigetSerializers() {
    Mutator m = createMutator(keyspace, is);
    m.addInsertion(5, cf, 
        HFactory.createColumn(10, new byte[0], is, bas));
    m.execute();
    
    MultigetSliceQuery<Integer, Integer,byte[]> query = HFactory.createMultigetSliceQuery(keyspace, is, is, bas);
    query.setColumnFamily(cf).setKeys(new Integer[]{5}).setColumnNames(new Integer[]{10});
    QueryResult<Rows<Integer,Integer,byte[]>> result = query.execute();
    System.out.println(result.toString());
  }
