用Caetand从Cassandra中读取动态列族

我必须将数据从一个集群迁移到另一个集群，对数据进行一些转换 . 我正在尝试使用Kettle来完成本教程：

http://wiki.pentaho.com/display/EAI/Cassandra+Input

但我试图从通过cli（在之前版本的Cassandra中）创建的动态列族中读取：

使用read_repair_chance = 0和gc_grace = 0创建列族FamilyMorphsIndividuals;

我像这样创建cassandra输入步骤：

当我点击show schema时会出现以下信息：

列族：IndividualMorphsIndividuals密钥验证器：org.apache.cassandra.db.marshal.BytesType列比较器：org.apache.cassandra.db.marshal.BytesType默认列验证器：org.apache.cassandra.db.marshal.BytesType读取修复机会：0.0 GC宽限期：0最小压缩阈值：4最大压缩阈值：32复制写入：true

Column metadata:

但是当我尝试预览该步骤时，我收到此错误：

有谁知道如何使用这种带水壶的柱系列进行操作？

谢谢
