Hive 面对java.lang.NoClassDefFoundError:org/joda/time/ReadableInstant错误，即使在类路径中添加了joda time库

我有一个使用joda时间库类的java类。我能够导入joda时间类并在eclipse中运行我的类

当我试图在配置单元环境中添加类时，我会遇到错误（java.lang.NoClassDefFoundError:org/joda/time/ReadableInstant）。甚至这个类也存在于类路径中，并且还显式地添加了joda时间jar。在joda时间罐中，org/joda/time/ReadableInstant已经存在

如果您有任何帮助/建议，我们将不胜感激。

在我的案例中，我也将joda-time.jar复制到了一个Hive公共库中，但这不是最好的解决方案。正在寻找其他解决方案。
