我的平台：CDH 5.10 Quickstart VM和Teradata TDEXPRESS 16 VM版本。 我正在使用Sqoop和Teradata JDBC驱动程序 - tdgssconfig.jar，teradata-connector-1.5.3.jar，terajdbc4.jar 我的sqoop作业失败，出现以下错误。
有什么建议吗？

答案 0 :(得分：0)
您已使用--append和lastmodified一起修改过。这是不正确的。请在下面找到它们之间的详细差异。
Sqoop支持两种类型的增量导入：追加和lastmodified。您可以使用--incremental参数指定要执行的增量导入的类型。
导入表时，应指定append模式，其中不断添加新行并增加行ID值。您可以使用--check-column指定包含行ID的列。 Sqoop导入检查列的值大于--last-value指定值的行。
Sqoop支持的备用表更新策略称为lastmodified模式。您应该在更新源表的行时使用此项，并且每次此类更新都会将最后修改的列的值设置为当前时间戳。
所以假设你的表有一些新的插入和sone net更新，你的Sqoop工作将是。
