我只是在猪的蜂巢和 HcatLoader 中尝试一些东西。我所做的是,在 Hive 中创建了一个视图,然后尝试通过我使用 HcatLoader 创建的视图将数据加载到猪中。但它似乎不起作用。我只是想确认有没有办法做到这一点?当我尝试使用 HcatLoader 在猪中加载视图时出现以下错误
events=使用 org.apache.hcatalog.pig.HCatLoader() 加载“ViewName”;转储事件;
当我使用任何 tableName 而不是 Hive 中的 View 时,它似乎可以工作。此外,它不会给出 Metastore 错误。正如它所说的在转储时成功连接到 metastore at load 语句,它崩溃并出现以下错误。
任何指针都会有所帮助。
谢谢, 阿图尔
