Question

我必须将代码从teradata迁移到hive ..使用sqoop从Teradata导入数据时，它失败了以下错误：

ERROR tool.ImportTool: Encountered IOException running import job: 
java.io.IOException: java.lang.RuntimeException: interface 
org.apache.hadoop.mapreduce.lib.db.DBWritable not

有人遇到过这样的问题吗？

Answer 1

您可以查看您正在使用的teradata连接器的版本。尝试使用不同版本的连接器jar。我遇到了从MySQL表导入并更改为早期版本的MySQL连接器的问题，解决了我的问题。
