Cassandra 带Etl汤匙的卡桑德拉

我刚刚碰到了同样的问题。 经过一些调查后，我通过复制以下文件进行修复

• 数据集成/lib/log4j-1.2.16.jar
• 数据集成/plugins/pentaho大数据插件/lib/slf4j-api-1.7.3.jar
• 数据集成/插件/pentaho大数据插件/lib/slf4j-log4j12-1.7.3.jar

to…/data integration/plugins/pentaho-cassandra-plugin/lib/directory仍处于中断状态：无法打开此步骤的对话框java.lang.NoClassDefFoundError:org/slf4j/LoggerFactory位于org.apache.thrift.transport.TIOStreamTransport。（TIOStreamTransport.java:38）位于org.pentaho.cassandra.legacy.CassandraConnection.openConnection（CassandraConnection.java:234）。。。

An unexpected error occurred in Spoon:
