kettle操作HIVE，可以链接，但不能取数的问题

进行hadoop copy file后，hive也可以在kettle进行脚本操作！

今天遇到一个问题，kettle采用“表输入”的方式获取数据，输出到文件或者库，问题：

2014/03/25 11:36:55 - hadoop_hive_test - ERROR (version 4.4.0-stable, build 17588 from 2012-11-21 16.02.21 by buildguy) : ERROR executing query: org.pentaho.di.core.exception.KettleDatabaseException:

检查链接配置，发现链接是可以的



根据错误提示：org.pentaho.di.core.exception.KettleDatabaseException

没做hadoop 2.20的配置前，kettle4.4是支持hive的取数

解决：

采用kettle5.0.1，配置hadoop 2.20的相关插件后，是可以了
