Question

当我尝试使用sqoop从hive中的SQL Server导入所有表时，它只能在表处于默认架构（dbo）时工作。

当表位于不同的模式中（并且有多个模式）时，导入失败并显示错误：

Answer 1

您可以导入特定架构的所有表。

尝试 - 最后使用-schema schemaName。

如果你正在创造一份工作，我无法保证这一点。

Answer 2

您可以在sqoop导入时将表列表作为schemaname.dbo.tablename..iterate传递，并在--query select * from schemaname.dbo.tablename

中使用它

当表在不同的模式中时，如何从SQL Server导入所有带sqoop的表？
