It depends on lots of details of your setup, such broad questions usually won't get answered since it may require writing a book to thoroughly explain all the details. Just try, and report the exact issues you encountered. |

数据平台升级,为了验证升级后,加工数据是否一致,需要并行验证,在两个hadoop(华为mrs)集群运行,例如同时产出数据表:A,通过spark sql 程序同时访问两个集群 表A join操作,验证数据内容是否完全一致。借助 kyuubi 运行spark sql。
这种方式能够配置两个hive catalog?每个集群开启了kerberos 认证。在一个spark session 中同时访问这两个catalog 的表吗?
