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 在本教程之后执行此操作：
http://wiki.pentaho.com/display/EAI/Cassandra+Input
但是我正在尝试从通过 cli（在以前版本的 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 IndividualMorphsIndividuals；
我创建这样的 cassandra 输入步骤：
当我单击显示架构时，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 写入时复制：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 Kettle 操作这种列族？
谢谢
