Pentaho Cassandra 输入：键空间中不存在列族

Question

我正在尝试在 Pentaho Spoon UI 中设置来自 Cassandra 的输入步骤。但是当我尝试显示架构或运行任务时，出现以下异常：

java.lang.Exception: The column family local does not seem to exist in the keyspace system

我可以使用 CQLSH 和 DevCenter 访问键空间中的表。我也尝试过其他键空间和表，只是得到了同样的错误。

任何想法都将不胜感激，因为我似乎无法在此处或其他论坛中找到此问题的任何先前答案。

Answer 1

所以回答我自己的问题。在 Pentaho 与几个人交谈过。它只是对缺少的 cassandra 版本的支持。我正在使用 PDI 勺子版本 4.4.0，它显然只会为 cassandra 提供高达 2.0 的支持。在 Cassandra 2.1 或更高版本中，对尚未添加到 PDI 的元结构进行了更改。
